Is your feature request related to a problem? Please describe.
This is from a customer request.
Background:
The customer is trying to qualify all their current Spark jobs. The number of spark jobs are so many that they have to write a customized UDF to make the qualification work distributed: #1347
In the PR above, the general IDEA is to do a two step thing in the UDF:
Step-1 has been proved not valid, as some essential files for step-2 doesn't produced by Scala code. It requires also the python side code. Also it doesn't support hdfs as output filesystem
Step-2 only accepts local file system, which is inconvinient for distributed work in their production environment.
Thus, this issue is created to ask for full-chain support for HDFS file system. The command line after this feature is supported can be imagined like below:
This should contribute to #1304
