Starting a JVM like below will start it with 256MB of memory, and will allow the process to use up to 2048MB of memory: java -Xmx2048m -Xms256m More about...memory management

Ok, it looks like an environmental issue with random entropy collection. There are several ways to solve it, pick your choice based on prod/non-prod requirements. There was a previous discussion with some suggestions here: https://community.hortonworks.com/questions/58436/hdf-20-handing-on-restart.html

After correcting values for hbase.regionserver.global.memstore.size and hfile.block.cache.size everything looks good.

Hi, Were you able to fix the issue? I see similar one popping on my end

Hi, sorry, no luck. Still suffering from MR2/YARN. I have no idea how it works. Right now I'm getting deadlock several times a day. I have single user which submits jpb. It has huge pool (32*8 mem and 4*CPU) and It has limit for 8 applications at once. Suddenly everything stops. What does it mean? Who can I get the idea of what's went wrong?
