[jira] [Created] (STORM-3675) Eliminate ps command and use /proc/ status in ServerUtils

Bipin Prasad created STORM-3675:
-----------------------------------

             Summary: Eliminate ps command and use /proc/<pid> status in ServerUtils
                 Key: STORM-3675
                 URL: https://issues.apache.org/jira/browse/STORM-3675
             Project: Apache Storm
          Issue Type: Improvement
          Components: storm-server
            Reporter: Bipin Prasad


In ServerUtils.java, the *ps* command is very expensive on loaded Linux system. when trying to determine if all worker processes are dead. Changed ownership or missing /proc/<pid> directory for should be sufficient to detect death of process.
