Kylin defines some config properties for Hadoop. For example,
mapred.task.timeout is defined in kylin_job_conf.xml. I have the same
property in my mapred-site.xml for Hadoop. Which value is taken when
running Kylin MR jobs for cube building?
The problem is: as I build a cube with a table of 3GB I got "Timed out
after 3600 secs Container killed by the ApplicationMaster" error for a
mapper task. In my mapred-site.xml I actually disabled the timeout by
setting mapreduce.task.timeout with value of 0. It seems that the system
takes the value from Kylin.
Note: I use mapreduce.task other than your mapred.task because for
hadoop 2.4.1 I do not see the property mapred.task.timeout.
Cheers,
