Subject [Hadoop Wiki] Update of "Hbase/HowToRelease" by DavidWang
Date Tue, 05 Jun 2012 16:52:29 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "Hbase/HowToRelease" page has been changed by DavidWang:
http://wiki.apache.org/hadoop/Hbase/HowToRelease?action=diff&rev1=11&rev2=12

   * Run unit tests on different hardwares: mac, windows, linux.
   * [[Hbase/PerformanceEvaluation]] describes the !PerformanceEvaluation test and a cluster.
 Releasing 0.1.0, a cluster configuration that had MR and datanodes running on all 4 cluster
members -- with the 'head' node carrying namenode, jobtracker, a datanode and a tasktracker
and all others a datanode and tasktracker -- and with hbase master on 'head' and a single
regionserver on another node, the hbase cluster was able to stay up running 4 concurrent clients
doing the sequentialWrite and randomWrite tests with the cluster cleaned between each run
all in the default heap of 1G: e.g. {{{$ ./bin/hadoop org.apache.hadoop.hbase.PerformanceEvaluation
randomWrite 4}}}  Of, note, the JVM was 1.6. !RandomWrite fails w/ 1.5.  Also, odd time the
randomWrite will fail with NSRE but more often than not passes.

+ Please also take a look at [[ReleaseCandidateTestMatrix]] and fill out as appropriate when
folks report their test results.  It is meant to be somewhat high-level as we want to encourage
folks to test RCs, and having very strict guidelines on test may be discouraging to some folks
who don't have a big setup, etc.
