Subject How to avoid stop-the-world GC for HBase Region Server under big heap size
Date Thu, 23 Aug 2012 06:06:25 GMT

We are running Region Server on big memory machine (70G) and set Xmx=64G.
Most heap is used as block cache for random read.
Stop-the-world GC is killing the region server, but using less heap (16G)
doesn't utilize our machines well.

Is there a concurrent or parallel GC option that won't block all threads?

Any thought is appreciated. Thanks.
