Description
There's a whole class of bugs that we've been revealing from trying out online altering in conjunction with other operations like splitting. HBASE-4729, HBASE-4794, and HBASE-4814 are examples.
It's not so much that the online altering code is buggy, but that it wasn't tested in an environment that permits splitting.
I think we should mark online altering as experimental in 0.92 and add a config to enable it (so it would be disabled by default, requiring people to enable for altering table schema).
