Re: running mapreduceCan you provide a bit more information ?Such as the
release of hadoop you're running.
BTW did you use 'ps' command to see the command line for 4383 ?
Cheers

Hi Once running mapreduce, it will appear an unavailable process.
Each time it will be like this.
3472 ThriftServer
3134 NodeManager
3322 HRegionServer
4383 -- process information unavailable
4595 Jps
2978 DataNode
I delete the process id in directory of /tmp/hsperfdata_yarn,
but it still appears again after running mapreduce .
