Hairong Kuang updated HBASE-3059:

Description: 
The test hung when I ran mvn test today. The jstack shows that a Writer thread 
hung at

"Thread-1" prio=10 tid=0x2aaad81d2800 nid=0x6ce9 in Object.wait() 
[0x40f37000]
   java.lang.Thread.State: WAITING (on object monitor)  at 
java.lang.Object.wait(Native Method)
  at 
org.apache.hadoop.hbase.regionserver.ReadWriteConsistencyControl.completeMemstoreInsert(ReadWriteConsistencyControl.java:130)
  -- locked <0x2aaac9fa0f50> (a java.lang.Object)
  at 
org.apache.hadoop.hbase.regionserver.TestReadWriteConsistencyControl$Writer.run(TestReadWriteConsistencyControl.java:56)
  at java.lang.Thread.run(Thread.java:619)

It seems to be caused by a race condition in 
ReadWriteConsistencyControl#completeMemStoreInsert. Accesses/updates of the 
value of memStoreRead should be done while holding the readWaiters lock.
