Brian Sutherland created BIGTOP-729:
---------------------------------------
Summary: zookeeper initd script status doesn't work
Key: BIGTOP-729
URL: https://issues.apache.org/jira/browse/BIGTOP-729
Project: Bigtop
Issue Type: Bug
Components: Init scripts
Reporter: Brian Sutherland
Priority: Minor
I have a situation where puppet is continually attempting to restart zookeeper.
It appears as if {{/etc/init.d/zookeeper-server status}} returns the wrong
answer in some cases. I can workaround this by setting the COLUMNS environment
variable just before the {{ps}} in hadoop_is_process_alive().
What is actually setting (or unsetting) this is a mystery, but I don't think
its right for the init script to break.

$ COLUMNS=80 ps -fp 2539 | grep 2539 | grep zookeeper >/dev/null ; echo $?
1
$ COLUMNS=1000 ps -fp 2539 | grep 2539 | grep zookeeper >/dev/null ; echo $?
0
{noformat}
It seems to me as if this method of using ps to check the daemon status is too
fragile.
