ASF GitHub Bot commented on GORA-443:

Github user cloudysunny14 commented on the issue:

    Thank you for comments.
    I think this is because of the reason as follows:
    First, BufferedMutation#flush is processed synchronously, 
    and a batch request (MultiRequest) is created from a buffered mutations.
    Then, RegionServer processes a MultiRequest as a minibatch(HRegion#doMiniBatchMutation)
that updates the timestamp of each cell to currentTime if Mutation has HConstants.LATEST_TIMESTAMP(by
    This operation apply all mutations in minibatch, therefore all cells has same timestamp.
    Since the HBaseStore#put create the Delete and Put as the MultiRequest, Puts are invisible.
    See Also:
    I'm sorry for my poor english :(
    I made this fix as a possible solution. (HACK)
    However, does not pass testDeleteByQueryFields yet.
    This is known issue GORA-472. I will create(reopen) the pull request for GORA-472 later.
    and I am trying to run all test..
