Any luck? I am having exceptionally bad (ugly) problems with x1.large instances (7.5Gb), Ubuntu, backed by EBS, Hbase + Hadoop (3 nodes) initially created by Whirr 0.6 (trunk, 2 months ago)
I suspect it is "virtualization", servers unpredictably stop on 5-10-15 minutes, I even increased ZooKeeper timeouts to 20 minutes but it doesn't helpĀ Virtualization related? GC shows user time ZERO, system time ZERO, and real time 600 seconds (just as a sample); in most cases (99.99%) all timings are zero (so it's tuned to the best) -- Fuad Efendi 416-993-2060 http://www.tokenizer.ca
