[hbase] If a region server cannot talk to the master after several attempts, it
should shut itself down
-------------------------------------------------------------------------------------------------------
Key: HADOOP-1960
URL: https://issues.apache.org/jira/browse/HADOOP-1960
Project: Hadoop
Issue Type: Improvement
Components: contrib/hbase
Affects Versions: 0.15.0
Reporter: Jim Kellerman
Assignee: Jim Kellerman
Fix For: 0.15.0
If a region server cannot contact the master after a configurable number of
tries, it should shut itself down.
If the region server cannot contact the master,
- if the master is alive but the network is partitioned, the master will
probably time out the region server's lease and try to recover the server's log
and reassign the regions the server is serving.
- if the master has died, and subsequently restarts, it will be reassigning
regions anyway, so the region server should stop serving the regions.
