# tFileInputFullRow properties for Apache Spark Batch

These properties are used to configure tFileInputFullRow running in the Spark Batch Job framework.

The Spark Batch tFileInputFullRow component belongs to the File family.

The component in this framework is available in all subscription-based Talend products with Big Data and Talend Data Fabric.

## Basic settings

| Properties | Description |
| --- | --- |
| Define a storage configuration<br>component | Select the configuration component to be used to provide the configuration<br>information for the connection to the target file system such as HDFS.<br><br>If you leave this check box clear, the target file system is the local<br>system.<br><br>The configuration component to be used must be present in the same Job.<br>For example, if you have dropped a tHDFSConfiguration component in the Job, you can select it to write<br>the result in a given HDFS system. |
| Property type | <ul> <li> <p>Either <span>Built-In</span> or <span>Repository</span>. </p> </li> <li> <p> <span>Built-In</span>: No property data stored centrally.</p> </li> <li> <p> <span>Repository</span>: Select the repository file where the            properties are stored.</p> <p>The properties are stored centrally under the <span>Hadoop                Cluster</span> node of the <span>Repository</span>            tree.</p> <p>For more information about the <span>Hadoop            Cluster</span> node, see <a href="https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/managing-hadoop-metadata" target="_blank">Managing Hadoop connection metadata</a>.</p> <p>The fields that come after are pre-filled in using the fetched                data.</p> </li> </ul> |
| Schema and Edit<br>Schema | <ul> <li> <p>A schema is a row description. It defines the number of fields            (columns) to be processed and passed on to the next component. When you create a Spark            Job, avoid the reserved word <kbd>line</kbd> when naming the            fields.</p> <p>Click <span>Edit schema</span> to make changes to                  the schema. If you make changes, the schema automatically becomes built-in. </p> </li> <li> <p> <span>Built-In</span>: You create and store the schema locally for this component                only.</p> </li> <li> <p> <span>Repository</span>: You have already created the schema and stored it in the                Repository. You can reuse it in various projects and Job designs.</p> </li> </ul> |
| Folder/File | Browse to, or enter the path pointing to the data to be used in the file system.<br><br>If the path you set points to a folder, this component will<br>read all of the files stored in that folder, for example,<br>/user/talend/in; if sub-folders exist, the sub-folders are automatically<br>ignored unless you define the property<br>spark.hadoop.mapreduce.input.fileinputformat.input.dir.recursive to be<br>true in the Advanced properties table in the<br>Spark configuration tab.<br><br><ul> <li>Depending on the filesystem to be used, properly configure the corresponding          configuration component placed in your Job, for example, a            <span>tHDFSConfiguration</span> component for HDFS, a            <span>tS3Configuration</span> component for S3 and a            <span>tAzureFSConfiguration</span> for Azure Storage and Azure Data Lake          Storage.</li> </ul><br><br>If you want to specify more than one files or directories in this<br>field, separate each path using a comma (,).<br><br>If the file to be read is a compressed one, enter the file name<br>with its extension; then tHDFSFullRow automatically decompresses it at<br>runtime. The supported compression formats and their corresponding<br>extensions are:<br><br><ul> <li> <p>DEFLATE: <em>*.deflate</em> </p> </li> <li> <p>gzip: <em>*.gz</em> </p> </li> <li> <p>bzip2: <em>*.bz2</em> </p> </li> <li> <p>LZO: <em>*.lzo</em> </p> </li> </ul><br><br>The button for browsing does not work with the Spark Local mode; if you are using the other Spark Yarn modes that Talend Studio<br>supports with your distribution, ensure that you have properly configured the connection<br>in a configuration component in the same Job. Use the configuration component depending<br>on the filesystem to be used. |
| Die on error | Select the checkbox to stop the execution of the Job when an error<br>occurs. |
| Row separator | The separator used to identify the end of a row. |
| Header | Enter the number of rows to be skipped in the beginning of file. |
| Skip empty rows | Select this checkbox to skip the empty rows. |

## Advanced settings

| Properties | Description |
| --- | --- |
| Set minimum partitions | Select this check box to control the number of partitions to be created from the input<br>data over the default partitioning behavior of Spark.<br><br>In the displayed field, enter, without quotation marks, the minimum number of partitions<br>you want to obtain.<br><br>When you want to control the partition number, you can generally set at least as many partitions as<br>the number of executors for parallelism, while bearing in mind the available memory and the<br>data transfer pressure on your network. |
| Custom Encoding | You may encounter encoding issues when you process the stored data. In that<br>situation, select this check box to display the Encoding list.<br><br>Then select the encoding to be used from the list or select<br>Custom and define it<br>manually. |

## Usage

| Usage guidance | Description |
| --- | --- |
| **Usage rule** | This component is used as a start component and requires an<br>output link.<br><br>This component, along with the Spark Batch component Palette it belongs to,<br>appears only when you are creating a Spark Batch Job.<br><br>Note that in this documentation, unless otherwise explicitly stated, a<br>scenario presents only Standard Jobs, that is to<br>say traditional<br>Talend<br>data integration Jobs. |
| Spark Connection | In the Spark<br>Configuration tab in the Run<br>view, define the connection to a given Spark cluster for the whole Job. In<br>addition, since the Job expects its dependent jar files for execution, you must<br>specify the directory in the file system to which these jar files are<br>transferred so that Spark can access these files:<br><br><ul> <li> <div> <span>Yarn mode</span> (Yarn client or Yarn cluster):<ul> <li> <p>When using Google Dataproc, specify a bucket in the                                            <span>Google Storage staging bucket</span>                                        field in the <span>Spark configuration</span>                                        tab.</p> </li> <li> <p>When using HDInsight, specify the blob to be used for Job                                        deployment in the <span>Windows Azure Storage                                            configuration</span> area in the <span>Spark                                            configuration</span> tab.</p> </li> <li>When using Altus, specify the S3 bucket or the Azure                                    Data Lake Storage for Job deployment in the <span>Spark                                        configuration</span> tab.</li> <li> <p>When using on-premises distributions, use                                        the configuration component corresponding to the file system                                        your cluster is using. Typically, this system is HDFS and so                                        use <a href="https://help.qlik.com/talend/r/en-US/8.0/components/hdfs/thdfsconfiguration">tHDFSConfiguration</a>.</p> </li> </ul> </div> </li> <li> <p> <span>Standalone mode</span>: use the                            configuration component corresponding to the file system your cluster is                            using, such as <a href="https://help.qlik.com/talend/r/en-US/8.0/components/hdfs/thdfsconfiguration-properties-for-apache-spark-batch">tHDFSConfiguration Apache Spark Batch</a> or <a href="https://help.qlik.com/talend/r/en-US/8.0/components/amazon-s3/ts3configuration-properties-for-apache-spark-batch">tS3Configuration Apache Spark Batch</a>.</p> <p>If you are using Databricks without any configuration component present                            in your Job, your business data is written directly in DBFS (Databricks                            Filesystem).</p> </li> </ul><br><br>This connection is effective on a per-Job basis. |
