----------------------------------
Summary: Giraph needs an admin script
Key: GIRAPH-312
URL: https://issues.apache.org/jira/browse/GIRAPH-312
Project: Giraph
Issue Type: New Feature
Components: conf and scripts, zookeeper
Affects Versions: 0.2.0
Reporter: Eli Reisman
Assignee: Eli Reisman
Priority: Minor
Fix For: 0.2.0
Our zookeeper instances have very long uptimes on our cluster, and failed job
trees are never cleaned from memory. There is a separate shell script to do
this, but its not picky about which node trees it erases, and on some systems
some Giraph users may not have access to it.
This patch will add a shell script to activate a new class which will use
Giraph conf file options or our normal -Dgiraph.XYZ command-line opts to get
the ZK quorum info, and clean out the remnants from its memory of old failed
and killed jobs. They do pile up over time.
This led to the larger idea that Giraph needs a general giraph-admin shell
script as a home for stuff like this. Jakob suggested it would be a good idea
to put this into such a script since then admin groups can be created so that
not every Giraph client can run it. This script currently only has code to
start up the zk cleaner, but can have more options added to it as JIRA's to add
features crop up.
