Date Tue, 01 Apr 2008 20:28:52 GMT
Dear Wiki user,

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

The following page has been changed by stack:
http://wiki.apache.org/hadoop/Hbase/HowToRelease

------------------------------------------------------------------------------
  Before the release, run the following smoke tests (at least).
  
  == Smoke Tests ==
-  * Run unit tests
+  * 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}}}

randomWrite will fail with NSRE but more often than not passes.
