[jira] [Updated] (BIGTOP-1038) PIDFILE in service scripts of Hadoop
is inconsistent with the path in hadoop-daemon.sh
[ https://issues.apache.org/jira/browse/BIGTOP-1038?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Masatake Iwasaki updated BIGTOP-1038:
-------------------------------------
Description:
PIDFILE in service scripts is fixed value because of variable expansion during packaging.

$ grep 'PIDFILE=' /etc/init.d/hadoop-*
/etc/init.d/hadoop-hdfs-datanode:PIDFILE="/var/run/hadoop-hdfs/hadoop-hdfs-datanode.pid"
/etc/init.d/hadoop-hdfs-namenode:PIDFILE="/var/run/hadoop-hdfs/hadoop-hdfs-namenode.pid"
/etc/init.d/hadoop-mapreduce-historyserver:PIDFILE="/var/run/hadoop-mapreduce/mapred-mapred-historyserver.pid"
/etc/init.d/hadoop-yarn-nodemanager:PIDFILE="/var/run/hadoop-yarn/yarn-yarn-nodemanager.pid"
/etc/init.d/hadoop-yarn-resourcemanager:PIDFILE="/var/run/hadoop-yarn/yarn-yarn-resourcemanager.pid"
{noformat}
However, HADOOP_IDENT_STRING composing pidfile path is configurable in hadoop-env.sh.
{noformat}
$ grep HADOOP_IDENT_STRING /usr/lib/hadoop/sbin/hadoop-daemon.sh
# HADOOP_IDENT_STRING A string representing this instance of hadoop. $USER by default
export HADOOP_IDENT_STRING=$HADOOP_SECURE_DN_USER
if [ "$HADOOP_IDENT_STRING" = "" ]; then
export HADOOP_IDENT_STRING="$USER"
chown $HADOOP_IDENT_STRING $HADOOP_LOG_DIR
export HADOOP_LOGFILE=hadoop-$HADOOP_IDENT_STRING-$command-$HOSTNAME.log
log=$HADOOP_LOG_DIR/hadoop-$HADOOP_IDENT_STRING-$command-$HOSTNAME.out
pid=$HADOOP_PID_DIR/hadoop-$HADOOP_IDENT_STRING-$command.pid
{noformat}
As a result, the path of pidfile matches only when HADOOP_IDENT_STRING is service user name which is the default.
