Date Thu, 13 Sep 2012 11:58:08 GMT

    [ https://issues.apache.org/jira/browse/HAMA-640?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13454841#comment-13454841

Thomas Jungblut commented on HAMA-640:

Hi Zhuang, this JIRA is just for development tracking. I would advise you to come to our user
mailing list and explain yourself.
We are aware of the memory hunger and improved in HAMA-596 which will be release with 0.6.0.

At least you have multiple options:
- increase the heap of each task in your job by lifting the -Xmx configuration property in
- use the trunk version (build for yourself)
- wait for the next release

I will close this, thanks for your report.

> When I test some small graphs PageRank on distributed environment, everything went all
right. When I upload a Larger graph(758Mb) on HDFS, the graph format is all the same, and
the PageRank went right on SuperStep 0,1,2, then job failed after that, out of memory. I didn't
change the examples, the test use the hama-examples pagerank.
