Writing data to the table
About this task
Configuring tHiveLoad
Procedure
Double-click tHiveLoad to open its
Component view.
Select the Use an existing connection
check box and from Component list, select
the connection configured in the tHiveConnection component you are using for this Job.
From the Load action field, select
LOAD to write data from the file
holding the sample data that is presented at the beginning of this
scenario.
In the File path field, enter the
directory where the sample data is stored. In this example, the data is
stored in the HDFS system to be used.
In the real-world practice, you can
use tHDFSOutput to write data into the HDFS
system and you need to ensure that the Hive application has the appropriate
rights and permissions to read or even move the data.
For further information about tHDFSOutput, see tHDFSOutput.
for further
information about the related rights and permissions, see the documentation
or contact the administrator of the Hadoop cluster to be used.
Note if you need to read data from a local file system other than the HDFS
system, ensure that the data to be read is stored in the local file system
of the machine in which the Job is run and then select the Local check box in this Basic settings view. For example, when the connection mode
to Hive is Standalone, the Job is run in
the machine where the Hive application is installed and thus the data should
be stored in that machine.
In the Table name field, enter the name
of the target table you need to load data in. In this scenario, it is
employees.
From the Action on file list, select
APPEND.
Select the Set partitions check box and
in the field that appears, enter the partition you need to add data to. In
this scenario, this partition is country='US'.
