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 "bsp.child.java.opts".
- use the trunk version (build for yourself)
- wait for the next release
I will close this, thanks for your report.
