Arpit Agarwal commented on HADOOP-15066: ---------------------------------------- The error is from {{hadoop_stop_daemon}} in _hadoop-functions.sh_. {code} pid=$(cat "$pidfile") kill "${pid}" >/dev/null 2>&1 ... cur_pid=$(cat "$pidfile") ... if [[ "${pid}" = "${cur_pid}" ]]; then rm -f "${pidfile}" >/dev/null 2>&1 else hadoop_error "WARNING: pid has changed for ${cmd}, skip deleting pid file" {code} It looks like jsvc auto-deletes the pid file when the process is killed with SIGTERM. The check for changed pid likely needs to be skipped if the pid file doesn't exist. > Spurious error stopping secure datanode > --------------------------------------- > > Key: HADOOP-15066 > URL: https://issues.apache.org/jira/browse/HADOOP-15066 > Project: Hadoop Common > Issue Type: Bug > Components: scripts > Affects Versions: 3.0.0 > Reporter: Arpit Agarwal > > Looks like there is a spurious error when stopping a secure datanode. > {code} > # hdfs --daemon stop datanode > cat: /var/run/hadoop/hdfs//hadoop-hdfs-root-datanode.pid: No such file or > directory > WARNING: pid has changed for datanode, skip deleting pid file > cat: /var/run/hadoop/hdfs//hadoop-hdfs-root-datanode.pid: No such file or > directory > WARNING: daemon pid has changed for datanode, skip deleting daemon pid file > {code} -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
