-------------------------------------
Summary: 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
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".
