Matteo Bertozzi commented on HBASE-9204:
----------------------------------------
I'm +1 on the 94 patch without the rpc timeout stuff,
not sure about the trunk one. It looks like that the fix is only on master
restart
what about regions assigned on clone or regions assigned after an hbck -fixMeta
(which should be the same as clone)
> An Offline SplitParent Region can be assigned breaking split references

> An offline split parent region can be assigned by using 'assign' from shell.
> This may trigger a compaction on the split parent region that should be
> offline, breaking the references of the two daughters.
> The easy way to test this is:
> * disable compactions
> * create a table and insert some row
> * split
> * shutdown the master (otherwise there's a state checked inside the
> AssignmentManager)
> * start the master
> * assign the region marked as OFFLINE => true, SPLIT => true (the compaction
> on region startup will probably break the reference of the two daughters)
