yangsongjie created OOZIE-2810:
----------------------------------
Summary: RM job was stuck when running with oozie
Key: OOZIE-2810
URL: https://issues.apache.org/jira/browse/OOZIE-2810
Project: Oozie
Issue Type: Improvement
Components: action, core, HA, workflow
Affects Versions: 4.3.0
Environment: hadoop2.7.2,centos7*3
Reporter: yangsongjie
Fix For: 4.3.0
I'm running a mapreduce wordcount job task on oozie. 2 jobs were submitted to
the yarn, and then the monitoring tasks running upto 99% were stuck. Wordcount
job has been 0%.
When I kill off the monitor job, wordcount job runs smoothly.
I use a cluster of 3 virtual machines, configuration is as follows:
Profile per VM: cores=2 memory=2048MB reserved=0GB usableMem=0GB disks=1
Num Container=3
Container Ram=640MB
Used Ram=1GB
Unused Ram=0GB
yarn.scheduler.minimum-allocation-mb=640
yarn.scheduler.maximum-allocation-mb=1920
yarn.nodemanager.resource.memory-mb=1920
mapreduce.map.memory.mb=640
mapreduce.map.java.opts=-Xmx512m
mapreduce.reduce.memory.mb=1280
mapreduce.reduce.java.opts=-Xmx1024m
yarn.app.mapreduce.am.resource.mb=640
yarn.app.mapreduce.am.command-opts=-Xmx512m
mapreduce.task.io.sort.mb=256
Is there any way to solve this, to make two jobs run smoothly and finish at the
same time ?
