Subject [jira] [Updated] (HBASE-6970) hbase-deamon.sh creates/updates pid file even when that start failed.
Date Wed, 10 Oct 2012 03:34:03 GMT

     [ https://issues.apache.org/jira/browse/HBASE-6970?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Lars Hofhansl updated HBASE-6970:
---------------------------------

    Description: 
We just ran into a strange issue where could neither start nor stop services with hbase-deamon.sh.

The problem is this:
{code}
    nohup nice -n $HBASE_NICENESS "$HBASE_HOME"/bin/hbase \
        --config "${HBASE_CONF_DIR}" \
        $command "$@" $startStop > "$logout" 2>&1 < /dev/null &
    echo $! > $pid
{code}

So the pid file is created or updated even when the start of the service failed. The next
stop command will then fail, because the pid file has the wrong pid in it.

Edit: Spelling and more spelling errors.
