Jingyun Tian updated HBASE-22049:
---------------------------------
Description:
Now the split procedure is to unassign the split parent region, thus the state
is CLOSED. And it only modify the regionInfo column during meta updating.
{code}
Put putParent = makePutFromRegionInfo(RegionInfoBuilder.newBuilder(parent)
.setOffline(true)
.setSplit(true).build(), time);
{code}
Thus if we want to recover the state from meta for a split parent region, its
state is CLOSED instead of SPLIT.
was:
After we modify some attributes of table, hbaseAdmin will getAlterStatus to
check if all region's attributes updated. It will skip opened region and split
region as the following code shows.
{code}
for (RegionState regionState: states) {
if (!regionState.isOpened() && !regionState.isSplit()) {
ritCount++;
}
}
{code}
But since now the split procedure is to unassign the split parent region, thus
the state is CLOSED， and the check will hang there until timeout.
> RegionStateStore cannot recover SPLIT state from Meta for split parent region
