# tHDFSRowCount

Reads a file in HDFS row by row in order to determine the number of rows this file contains.

tHDFSRowCount counts the number of rows in a file in HDFS. If the file to be processed is a Hadoop sequence file type or a large dataset, it is recommended to use a tAggregateRow to count the records.
