Graham Gear created WHIRR-636:
---------------------------------
Summary: Default HADOOP_PID_DIR out of sync with CDH4
namenode/datanode service scripts
Key: WHIRR-636
URL: https://issues.apache.org/jira/browse/WHIRR-636
Project: Whirr
Issue Type: Bug
Reporter: Graham Gear
Priority: Minor
whirr-hadoop-default.properties currently includes:
hadoop-env.HADOOP_PID_DIR=/var/run/hadoop
This is at odds with the CDH4 hadoop-hdfs-datanode and hadoop-hdfs-namenode
which hardcodes PID file dirs within /var/run/hadoop-hdfs.
This means the namenode and datanode service scripts do not report correct
statuses. Updating HADOOP_PID_DIR to match the System V init scripts resolves
the issue.
This may well be an issue with the System V init scripts, which should refer to
the HADOOP_PID_DIR variable rather than the hardcoded value they have today (as
per job tracker script etc) - where do think we should address this?
