Correct me if im wrong. But looks like if you have A and B region server that has index and primary table then possible situation like this.
A and B under writes on table with indexes A - crash B failed on index update because A is not operating then B starting aborting A after restart try to rebuild index from WAL but B at this time is aborting then A starting aborting too From this moment nothing happens (0 requests to region servers) and A and B is not responsible from Master-status web interface > On 9 Sep 2018, at 04:38, Batyrshin Alexander <0x62...@gmail.com> wrote: > > After update we still can't recover HBase cluster.
