Ray Chiang commented on MAPREDUCE-6613: --------------------------------------- [~aw], I had specifically put a target version of 3.0, since this is "under the covers" not backwards compatible. Even in that case, would you consider that unacceptable? > Change mapreduce.jobhistory.jhist.format default from json to binary > -------------------------------------------------------------------- > > Key: MAPREDUCE-6613 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6613 > Project: Hadoop Map/Reduce > Issue Type: New Feature > Affects Versions: 2.8.0 > Reporter: Ray Chiang > Assignee: Ray Chiang > Priority: Minor > Attachments: MAPREDUCE-6613.001.patch > > > MAPREDUCE-6376 added a configuration setting to set up .jhist internal format: > mapreduce.jobhistory.jhist.format > Currently, the default is "json". Changing the default to "binary" allows > faster parsing, but with the downside of making the file not output friendly > by using "hadoop fs cat". -- This message was sent by Atlassian JIRA (v6.3.4#6332)
