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 .
