stack commented on HBASE-14678:
-------------------------------

What I removed:

diff --git a/hbase-server/src/test/java/org/apache/hadoop/hbase/TestPartialResultsFromClientSide.java b/hbase-server/src/test/java/org/apache/hadoop/hbase/TestPartialResultsFromClientSide.java
diff --git a/hbase-server/src/test/java/org/apache/hadoop/hbase/master/balancer/TestStochasticLoadBalancer.java b/hbase-server/src/test/java/org/apache/hadoop/hbase/master/balancer/TestStochasticLoadBalancer.java
diff --git a/hbase-server/src/test/java/org/apache/hadoop/hbase/master/balancer/TestStochasticLoadBalancer2.java b/hbase-server/src/test/java/org/apache/hadoop/hbase/master/balancer/TestStochasticLoadBalancer2.java
diff --git a/hbase-server/src/test/java/org/apache/hadoop/hbase/master/procedure/TestMasterFailoverWithProcedures.java b/hbase-server/src/test/java/org/apache/hadoop/hbase/master/procedure/TestMasterFailoverWithProcedures.java
diff --git a/hbase-shell/src/test/java/org/apache/hadoop/hbase/client/TestReplicationShell.java b/hbase-shell/src/test/java/org/apache/hadoop/hbase/client/TestReplicationShell.java
diff --git a/hbase-shell/src/test/java/org/apache/hadoop/hbase/client/TestShell.java b/hbase-shell/src/test/java/org/apache/hadoop/hbase/client/TestShell.java

On branch-1, added TestAssignmentManager to removal list. It is failing pretty reliably... just needs a fix but removing it for now.

Leaving issue open because will put back these tests regardless.

> Looking at recent builds of 1.2, I see a few of the runs finishing with kills and notice that a JVM exited without reporting back state. Running the hanging test finder, I can see at least that in one case that the balancer tests seem to be outstanding; looking in test output, seems to be still going on.... A few others are reported as hung but they look like they have just started running and are just killed by surefire.
> This issue is about trying to disable a few of the problematics like balancer tests to see if our overall stability improves. If so, I can concentrate on stabilizing these few tests. Else will just undo the experiment and put the tests back on line.
