>            Reporter: 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".
