[jira] [Created] (MAPREDUCE-7008) Partitioner need to get input as
comand also instead of only java class.
Devendra Bhat created MAPREDUCE-7008:
----------------------------------------
Summary: Partitioner need to get input as comand also instead of only java class.
Key: MAPREDUCE-7008
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7008
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: contrib/streaming, performance, yarn
Affects Versions: 2.7.4
Environment: Cloudera version 5.13.
Reporter: Devendra Bhat
Priority: Critical
Streaming allows both commands and Java classes to be specified as mapper, reducer, and combiner, but the -partitioner option is still limited to Java classes only. Allowing commands to be specified as partitioner as well would greatly improve the flexibility of Streaming programs.
