Set the ZK timeout to something like 40ms, and give the GC enough Xmx so you never risk entering the much dreaded concurrent-mode-failure whereby the entire heap must be GCed.
Consider testing Java 7 and the G1 GC. We could get a JNI thread to do this, but no one has done so yet. I am personally hoping for G1 and in the meantime overprovision our Xmx to avoid the concurrent mode failures. -ryan On Tue, Oct 27, 2009 at 2:59 PM, Zhenyu Zhong <zhongresea...@gmail.com> wrote: > Ryan, > > Thank you very much. > May I ask whether there are any ways to get around this problem to make > HBase more stable? > > best, > zhong > > > > On Tue, Oct 27, 2009 at 4:06 PM, Ryan Rawson <ryano...@gmail.com> wrote: > >> There isnt any working code yet.
