Heng Chen commented on HBASE-16224:
-----------------------------------
{code}
+ TaskCheckerHost checker = createTaskCheckerHost(tableName);
{code}
Could we do it out of {{while}} scope?
Could you add some comments about interface TaskChecker?
Let me take a deep sight into patch v8, it is much more complicated than v1.
Will come back later.

> This patch is proposed to reduce the number of RPC for the large PUTs
> The number and data size of write thread(SingleServerRequestRunnable) is a
> result of three main factors：
> 1) The flush size taken by BufferedMutatorImpl#backgroundFlushCommits
> 2) The limit of task number
> 3) ClientBackoffPolicy
> A lot of threads created with less MUTATIONs is a result of two reason: 1)
> many regions of target table are in different server. 2) flush size in step
> one is summed by “all” server rather than “individual” server
> This patch removes the limit of flush size in step one and add maximum size
> to submit for each server in the AsyncProcess
