[jira] [Updated] (TEZ-2377) RandomWriter ends up using
TextOutputFormat instead of SequenceFileOutputFormat
[ https://issues.apache.org/jira/browse/TEZ-2377?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rajesh Balamohan updated TEZ-2377:
----------------------------------
Attachment: TEZ-2377.1.patch
[~bikassaha], [~sseth], [~zjffdu] - Please review. Test is not included. Tez was using "jobConf.getUseNewMapper()" earlier, and hence was working in earlier releases. But this got changed to "jobConf.getUseNewReducer()" as a part of TEZ-2162.
