Subject [jira] [Created] (BIGTOP-20) hard-coded pid location in Hadoop init.d scripts
Date Fri, 12 Aug 2011 21:53:29 GMT
hard-coded pid location in Hadoop init.d scripts
------------------------------------------------

                 Key: BIGTOP-20
                 URL: https://issues.apache.org/jira/browse/BIGTOP-20
             Project: Bigtop
          Issue Type: Bug
            Reporter: Roman Shaposhnik
            Priority: Minor


The init.d scripts installed as part of CDH3b3 RPMs have a hard-coded PID file, e.g.:

PIDFILE="/var/run/hadoop-0.20/hadoop-$HADOOP_IDENT_STRING-namenode.pid"

The init scripts should instead respect the values set in hadoop-env.sh

Current work-around is to set HADOOP_PID_DIR in hadoop-env.sh to /var/run/hadoop-0.20. Note
that HADOOP_IDENT_STRING must be set to the same value in both /etc/default/hadoop-0.20 and
hadoop-env.sh for the pid file to be found. It defaults to "hadoop" in /etc/default/hadoop-0.20.
