---------------------------------------------------------------------------
bq. Rajeshbabu Chintaguntla? How will the online region test typically perform
on a real cluster? Will we get false positives?
James in the real clusters region online check done by looking at master UI
which gives any regions in transition to open or run HBase Hbck on a table to
check any inconsistencies in the table(this gives regions in failed to open or
in transition also). In both the cause HBaseAdmin#getClusterStatus() will be
called. This gives the details about the regions in transition in the cluster
but not specific to table. This can give false positives when the regions
assigned to region servers but still yet to remove from the transition list.
I think we can make use of it and find specific patterns like any regions in
FAILED_OPEN or FAILED_CLOSE states which means the region won't be assigned for
longer (some times need manual intervention) otherwise the regions will be
quickly assigned in fraction of seconds and we are fine to continue rebuilding.
