Dave Marion commented on ACCUMULO-925: -------------------------------------- Is there a reason why we can't apply this back to 1.6? > Launch scripts should use a PIDfile > ----------------------------------- > > Key: ACCUMULO-925 > URL: https://issues.apache.org/jira/browse/ACCUMULO-925 > Project: Accumulo > Issue Type: Improvement > Components: scripts > Reporter: Christopher Tubbs > Assignee: Billie Rinaldi > Fix For: 1.8.0 > > Attachments: ACCUMULO-925.1.patch, ACCUMULO-925.2.patch > > Time Spent: 10m > Remaining Estimate: 0h > > Start scripts should create PIDfiles to store the PID of running processes in > a well known location (example: /var/run/accumulo/tserver.pid or > $ACCUMULO_HOME/tserver.pid), for the following benefits: > # Identify running services on a machine without executing and parsing the > system process list, so stop scripts can kill them when they are unresponsive. > # Prevent multiple instances of the same application from starting up (an > environment variable for the location of the PIDfile can be used to allow > multiple instances if it is desirable to do so). > # Potentially provide an alternate mechanism for terminating a process by > deleting its PIDfile rather than its lock in Zookeeper. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
