bq. If you have a use case, can u tell us how u use it and return bypass = true
I have no use case about the bypass=true, yet I have a observer which
transforms the specified PUT into another one(PUT) by preBatchMutate(). The
origin PUT will be skipped after transforming. The observer is working via the
Table#put, nevertheless it isn't working via the Table#mutateRow.
Although I don't submit the data via the Table#mutateRow, it seems to me that
the different write flows should have the same use of preBatchMutate() (and
other cp hook).

I have no use case about the bypass=true, yet I have a observer which
transforms the specified PUT into another one(PUT) by preBatchMutate(). The
origin PUT will be skipped after transforming. The observer is working for the
Table#put, nevertheless it fails for the Table#mutateRow.
Although I don't call the Table#mutateRow for the observer, I'm not sure that
the inconsistent behavior of preBatchMutate() (and other cp hooks) is good.

> Project: HBase
> Issue Type: Bug
> Reporter: ChiaPing Tsai
> Priority: Minor
> Attachments: HBASE-16933.v0.patch
>
>
> The scenario is similar to
> [HBASE-15417|https://issues.apache.org/jira/browse/HBASE-15417].
> The MultiRowMutationProcessor has the incorrect usage of bypassed mutations.
> This patch makes some incompatible change shown below.
> # If any mutation is bypassed, all mutations will be bypassed. Because the
> RowMutations is an atomic operation.
> # No CP post-hook will be called if the all mutations are bypassed. For
> example, postPut, postDelete, and postBatchMutate
