It seems that the both UT failures are xml related. Will submit a blank commit to trigger the QA again. |

This is a big behavior change. I suggest you send an email to both dev and user mailing list to clearly describe the old behavior and new behavior, to collect more feedbacks from the community. Thanks. |

Did you meet some issues that make you separate these configs to resolve them? I don't think an additional "hbase.block.enabled" is needed, this will make users confused with which meaning of 'block' here. For the meta blocks the cache should not be disabled, and this is the original design.

Right, these changes seems a little bit superfluous. In this case, may I just close this MR and the corresponding jira ticket?
