Hello,
I am running HBase 1.4.10 on AWS EMR 5.29.0 and have had issues after
some of our Region Servers restart (due to a variety of reasons) and the
cluster enters an inconsistent state after they come back up.
Running hbck, I am presented with many instances of:
ERROR: Empty REGIONINFO_QUALIFIER found in hbase:meta
I am able to resolve this issue by running:
"hbase hbck -fixEmptyMetaCells"
However, this is only a fix until the next time one of our region
servers restart which is currently a daily event. Does anyone know how
to prevent this issue from occurring in the first place? It looks like
our Region Server was in the middle of splitting and compaction
operations before aborting.
I've noticed that writing to hbase while these errors are present can
result in ingest issues within our application so I'd really like to
understand how the meta table can get into this state.
Thanks,
Mike
