[jira] [Comment Edited] (MAPREDUCE-7191) JobHistoryServer should
log exception when loading/parsing history file failed
[ https://issues.apache.org/jira/browse/MAPREDUCE-7191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16787508#comment-16787508 ]

Sure, thanks [~yangjiandan] for filing the issue.
It seems the old code throws the exception with the trace.
{code:java}
try { ... } catch (IOException e) {
throw new YarnRuntimeException("Could not load history file " + historyFileAbsolute, e);
}
{code}
What happened that is not getting exposed in the log? Is it being caught and ignored on the upper layer?

> 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"

> 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.
