stack 50161f2de4 HBASE-24034 [Flakey Tests] A couple of fixes and cleanups
hbase-rsgroup/src/test/java/org/apache/hadoop/hbase/rsgroup/TestRSGroupMajorCompactionTTL.java
 Remove spurious assert. Just before this it waits an arbitrary 10
 seconds. Compactions could have completed inside this time. The spirit
 of the test remains.

hbase-server/src/main/java/org/apache/hadoop/hbase/master/cleaner/HFileCleaner.java
 Get log cleaner to go down promptly; its sticking around. See if this
 helps with TestMasterShutdown

hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/wal/FSHLog.java
 We get a rare NPE trying to sync. Make local copy of SyncFuture and see
 if that helps.

hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestAsyncRegionAdminApi.java
 Compaction  may have completed when not expected; allow for it.

hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestBlockEvictionFromClient.java
 Add wait before testing. Compaction may not have completed. Let
 compaction complete before progressing and then test for empty cache.

hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestMasterShutdown.java
 Less resources.

hbase-server/src/test/java/org/apache/hadoop/hbase/master/balancer/TestDefaultLoadBalancer.java
 Less resources.

hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestEndToEndSplitTransaction.java
 Wait till online before we try and do compaction (else request is
 ignored)

hbase-server/src/test/java/org/apache/hadoop/hbase/tool/TestCanaryTool.java
 Disable test that fails randomly w/ mockito complaint on some mac os
 x's.

TestMasterShutdown... fix NPE in RSRpcDispatcher... catch it and covert
to false and have master check for successful startup.

Apache HBase [1] is an open-source, distributed, versioned, column-oriented
store modeled after Google' Bigtable: A Distributed Storage System for
Structured Data by Chang et al.[2]  Just as Bigtable leverages the distributed
data storage provided by the Google File System, HBase provides Bigtable-like
capabilities on top of Apache Hadoop [3].

To get started using HBase, the full documentation for this release can be
found under the doc/ directory that accompanies this README.  Using a browser,
open the docs/index.html to view the project home page (or browse to [1]).
The hbase 'book' at http://hbase.apache.org/book.html has a 'quick start'
section and is where you should being your exploration of the hbase project.

The latest HBase can be downloaded from an Apache Mirror [4].

The source code can be found at [5]
