Enis Soztutar commented on PHOENIX-3045:
----------------------------------------
Indeed, if there is a workaround for this issue, it maybe fine to defer, but it
seems that this will result in data tables region to be permanently offline.
> Data regions in transition forever if RS holding them down during drop index
> and before flush on data table

> Currently we are flushing data table after dropping the index so that region
> opening won't be failed to recover dropped index edits. But there is a chance
> that region server holding the data regions might abruptly killed before
> flushing the data table this leads same failure case that data regions won't
> be opened which leads to the regions in transition forever. We need to handle
> this case by checking dropped indexes on recovery write failures and skip the
> corresponding mutations to write to them.
