Akira AJISAKA created HDFS-7708: ----------------------------------- Summary: Balancer should delete its pid file when it completes rebalance Key: HDFS-7708 URL: https://issues.apache.org/jira/browse/HDFS-7708 Project: Hadoop HDFS Issue Type: Bug Components: balancer & mover Affects Versions: 2.6.0 Reporter: Akira AJISAKA
When balancer completes rebalance and exits, it does not delete its pid file. Starting balancer again, then "kill -0 pid" to confirm the process is running. The problem is: * If another process is running as the same pid as `cat pidfile`, balancer fails to start with following message: {code} balancer is running as process 3443. Stop it first. {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
