Unable to detect running process from pid file
----------------------------------------------
Key: HADOOP-5316
URL: https://issues.apache.org/jira/browse/HADOOP-5316
Project: Hadoop Core
Issue Type: Bug
Components: contrib/chukwa
Environment: Redhat EL 5.1, Java 6
Reporter: Eric Yang
Assignee: Eric Yang
Priority: Trivial
Linux ps command output produces white space in front of the pid number, if the
pid is lesser than 5 digits number. The current shell script does not parse
this correctly for watchdog. In addition, CHUKWA_PID_DIR needs to be better
supported by chukwa's shell script. In some of the shell scripts, the
reference to pid file is in CHUKWA_HOME/var/run, and this should be changed to
CHUKWA_PID_DIR.
