Jim Kellerman updated HADOOP-1960:
----------------------------------
Attachment: patch.txt
This patch removes the new unit test for testing region server shutdown because
the change to HMaster (adding an abort() method), is too dangerous to leave
enabled. Without the test, changes to HMaster and MiniHBase cluster are no
longer needed.
Changes included in this patch are:
TestRegionServerAbort
- Add check for scanner != null before trying to close it
TestSplit
- Enclose test body in try catch block so that exceptions can be dumped to the
console at the point in the test where they occur.
HRegionServer
- If unable to communicate with the master for more than the lease timeout
interval abort server.
> [hbase] If a region server cannot talk to the master after several attempts,
> it should shut itself down

> 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.
