> I'm test rolling 2.7.2 to 3.2.0.
> RM& NM has upgrade to 3.2.0, JobHistoryServer is still 2.7.2.
> When submitting MR job using 3.2.0 client I found JobHistory URL could not
> open, and in webpage showing "Could not load history file
> hdfs://NameNode:8020/tmp/hadoop-yarn/staging/history3/done/2019/03/06/000000/job_1551697798944_0020****.jhist"
> There are only loading log just like following and no exception info in log
> file of JobHistoryServer.

> {code}
> After I add some log when loading history file failed I get following
> exception. 3.2.0 write jhist files using *binary* format, but 2.7.2 using
> *json* format. After I set mapreduce.jobhistory.jhist.format=json in 3.2.0
> client configuration, I can get job info from jhs.
> There is still no log in Hadoop-3.2.0, I think it's very helpful to add some
> log to debug.
