> 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.
