-----------------------------------

Can we clear the parent region state during split ?
{quote}
Maybe not. IIRC, the actual HFiles are still placed under the directory for the
parent issue, so if we need the region state from meta, the HFiles will be
deleted... The CatalogJaniter will delete the region state when we find that
there are no references to the HFiles.
> Client application may get stuck (time bound) if a table modify op is called
