Eli Collins commented on HDFS-4200:
-----------------------------------
This is great Suresh. The following hbase test (run from hbase trunk) is a good
stress test of the synchronization in this code. If you want to run it with
your change you need to publish your change to a local mvn repo (using the same
hadoop version in the hbase pom).
{code}
mvn test -Dtest=TestMiniClusterLoadSequential -P localTests
-DredirectTestOutputToFile=true -Dhadoop.profile=2.0
{code}
