Generate the Source File Name

Generate the Source File Name

You can generate the source file name for the flat file data object. The content of the file name column remains consistent across different modes of execution.
When you push processing to the specific engine for the required file types, the file name column returns the path based on the following formats:
Run-time Engine
Source File Location
Returned Path
Blaze
Local system
<staged path><local file path>
For example,
hdfs://host name:port/hive/warehouse/home/devbld/Desktop/ff.txt
Spark
HDFS
hdfs://<host name>:<port>/<file name path>
For example,
hdfs://host name:port/hive/warehouse/ff.txt
Spark
Local system
<local file path>
For example,
/home/devbld/Desktop/ff.txt
The file name column returns the content in the following format for a high availability cluster:
hdfs://<host name>/<file name path>
For example,
hdfs://irldv:5008/hive/warehouse/ff.txt
