+1. On a 5 node test cluster, loaded 100M rows (~170G on disk) using YCSB, did some mixed workload (increment, scan, read, put). No GC pauses. Killed a server while under load, recovered correctly.
Along the way I accidentally deleted my ZK jar while the cluster was running, which left a couple regions unassigned. hbck -fix fixed them. Also, the new feature that checks for out-of-date hbase-default.xml detected that I had left one lying around on the classpath from a previous version, so that works! :) -Todd On Wed, Feb 16, 2011 at 11:03 AM, Stack <[email protected]> wrote: > +1 > > Downloaded, reviewed doc., and checked it runs locally. > > Put it up on cluster, ran some YCSBs -- I deployed a snapshot of RC1 > to apache maven snapshot repo with name 0.90.1-20110215.213202-4 if > anyone needs it -- and all seemed to run fine in basic write and > read/write scenarios.
