Retaining locality after restart broken
---------------------------------------
Key: HBASE-4402
URL: https://issues.apache.org/jira/browse/HBASE-4402
Project: HBase
Issue Type: Bug
Components: master
Affects Versions: 0.92.0
Reporter: Todd Lipcon
Priority: Blocker
Fix For: 0.92.0
In DefaultLoadBalancer, we implement the "retain assignment" function like so:
{code}
if (sn != null && servers.contains(sn)) {
assignments.get(sn).add(region.getKey());
{code}
but this will never work since after a cluster restart, all servers have a new
ServerName with a new startcode.
