> in the same cluster, one install a trafodion version.
> then use trafodion_uninstaller to remove the installation.
> later at same cluster, install again via trafodion_install
> after the new installation, dcscheck fail.
> jps cannot show related DCS java processes, but those processes are up and 
> running.
> It is due to a legacy /tmp/hsperfdata_trafodion direcotry belong to the 
> previous trafodion user. The new user cannot write into this folder, but jps 
> rely on it to work correct. And dcscheck rely on jps to work correctly.
> Either installer remove that legacy directory, or uninstaller remove it.
