I got the following test failures for the attached patch.
These two failed both in test suite and individually.

> Improvements in tests
> ---------------------
>
> Key: HBASE-4703
> URL: https://issues.apache.org/jira/browse/HBASE-4703
> Project: HBase
> Issue Type: Improvement
> Components: test
> Affects Versions: 0.92.0
> Environment: all
> Reporter: nkeywal
> Assignee: nkeywal
> Priority: Minor
> Attachments: 20111030_4703_all.patch, 20111030_4703_all.v2.patch
>
>
> Global:
> - when possible, make the test using the default cluster configuration for
> the number of region (1 instead of 2 or 3). This allows a faster stop/start,
> and is a step toward a shared cluster configuration.
> - 'sleep': lower or remove the sleep based synchronisation in the tests (in
> HBaseTestingUtility, TestGlobalMemStoreSize, TestAdmin,
> TestCoprocessorEndpoint, TestHFileOutputFormat, TestLruBlockCache,
> TestServerCustomProtocol, TestReplicationSink)
> - Optimize 'put' by setting setWriteToWAL to false, when the 'put' is big
> or in a loop. Not done for tests that rely on the WAL.
>
> Local issues:
> - TestTableInputFormatScan fully deletes the hadoop.tmp.dir directory on
> tearDown, that makes it impossible to use in // with another test using this
> directory
> - TestIdLock logs too much (9000 lines per seconds). Test time lowered to 15
> seconds to make it a part of the small subset
> - TestMemoryBoundedLogMessageBuffer useless System.out.println
> - io.hfile.TestReseekTo useless System.out.println
> - TestTableInputFormat does not shutdown the cluster
> - testGlobalMemStore does not shutdown the cluster
> - rest.client.TestRemoteAdmin: simplified, does not use local admin, single
> test instead of two.
> - HBaseTestingUtility#ensureSomeRegionServersAvailable starts only one
> server, should start the number of missing server instead.
> - TestMergeTool should starts/stops the dfs cluster with HBaseTestingUtility
