failed to get oozie log in hue

[#1]

as CDHer knows, when you execute workflow like hive , sqoop, you can see the oozie log in the hue, even the job finished.

but recently, i just can see oozie log when the job is running, if the job has been finished,, there is no any log.

i don;t know why,. i has changed some parameter, but all of changes just for memory or other performance parameter, no log paramter changes,.

anybody knows this iisue plase give me sme advises if  you have this kind expericnece, thanks.

[#2]

give you some message for debug:

when i click stdout, there just show me :


Log Upload Time: Fri Jan 08 19:25:15 +0800 2016

Log Length: 0


Cloudera Supporter, why the log Length is 0? any parameter can change it's back

[#3]

Hi, CDH supporter,  could you give me some advises, why the oozie logs can't find in job browse after the job finished, but i can find it when the job is in running state.

[#4]

When a job goes to completed state, logs are moved from the local node to Job history server. 

Is your 'mapreduce.jobhistory.max-age-ms' set to '0' in yarn configuration in CM ?

got resolved.

i think this is a bug,  i have chaged reduce vcore to 2 from 1, then i can't see the logs.  after check all the change history, i really don't believe this change will cause log disapper, so i didn';t change it back. at last i have no any idea, then change it's back to 1, it's ok now.
