Subject Java Process Memory Leak
Date Mon, 17 Mar 2014 14:56:15 GMT
Hi all,

With Giraph 1.0.0, I've noticed an issue where the Java process
corresponding to the job loiters around indefinitely even after the job
completes (successfully). The process consumes memory but not CPU time.
This happens on both a single machine and clusters of machines (in which
case every worker has the issue). The only way I know of fixing this is
killing the Java process manually---restarting or stopping Hadoop does not

Is this some known bug or a configuration issue on my end?
