Hi
I'm using Hadoop2.7 with cgroup enabled on Redhat7.1.
When I run large MR jobs, some nodemanager machine auto reboot.
If I use DefaultLCEResourcesHandler instead of CgroupsLCEResourcesHandler,
The MR jobs run fine.
HiI'm using hbase with about 20 regionserver. And one regionserver failed
to write most of datanodes quickly, finally cause this regionserver die. While
other regionserver is ok.
logs like this:java.io.IOException: Bad response ERROR for block
are you using ?
Have you run fsck ?
Cheers

I don't see error or exception either.
Perhaps search in wider scope.
