-------------------------------------
Summary: the code for handling when rs.isSplit() inside
AM.nodeDeleted is dead code, should be removed
Key: HBASE-7058
URL: https://issues.apache.org/jira/browse/HBASE-7058
Project: HBase
Issue Type: Bug
Components: master
Affects Versions: 0.92.1
Reporter: Tianying Chang
Assignee: Tianying Chang
Priority: Minor
I am reading the code related to region split. I feel that this code below in
AssignmentManager seems to be dead code. Because 1) I don't see any place that
callls to update the regionState to be State.SPLIT. 2) for scenario when region
has already been split and RS crashed, ServerShutdownHandler should have
already taken care of it.
Am I missing something here. If not, I would suggest to remove it.
if (rs.isSplit()) {
LOG.debug("Ephemeral node deleted, regionserver crashed?, " +
"clearing from RIT; rs=" + rs);
regionOffline(rs.getRegion());
