    External issue ID:   (was: HDFS-14308)

> When the data directory is set to EC,the amount of storefiles reaches a 
> relatively high level,heap Occupancy Percent is above heap occupancy alarm 
> watermark,resulting in frequent gc and eventual failure

> When the data directory is set to EC, during the continuous load process, 
> regionserver is found down ,to view the log:
> regionserver.HeapMemoryManager: heapOccupancyPercent 0.91630864 is now below 
> the heap occupancy alarm watermark (0.95)
> regionserver.HeapMemoryManager: heapOccupancyPercent 0.969546 is above heap 
> occupancy alarm watermark (0.95)
> [JvmPauseMonitor] util.JvmPauseMonitor: Detected pause in JVM or host machine 
> (eg GC): pause of approximately 1254ms
>  GC pool 'G1 Young Generation' had collection(s): count=2 time=115ms
>  GC pool 'G1 Old Generation' had collection(s): count=1 time=1487ms
> In particular, GC pauses occurred 283 times in half an hour.
> The memory analysis found that most of the memory footprint was generated by 
> HeepByteBuffer,and DFSStripedInputStream produces the HeepByteBuffer
