----------------------------------
Summary: JMap Dumper
Key: GIRAPH-522
URL: https://issues.apache.org/jira/browse/GIRAPH-522
Project: Giraph
Issue Type: Bug
Reporter: Nitay Joffe
Assignee: Nitay Joffe
We've been using this for our jobs for a while now and figured we would
contribute it back. This is an observer for both worker and master (in other
words for every node) that periodically dumps the output of "jmap -histo". This
has been very handy for us in debugging memory issues and seeing what
allocations are happening.
