> 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".
