HADOOP-2392 HADOOP-2324 HADOOP-2396 HADOOP-2397


HADOOP-2392, HADOOP-2324:

Chore
- initialChore() now returns boolean

HMaster
- rather than retry in root and meta scanners, return if a scan fails. It will get retried on the next scan. This has two effects: 1) scanners exit more quickly during shutdown and 2) they don't keep retrying to connect to a dead server, allowing them to recover from a server going down more quickly.
- initialScan in root and meta scanners return boolean and do not progress to maintenanceScan until the initial scan completes successfully.

HRegionServer
- speed up region server exit by reordering join's so that we join with threads in the order that we told them to stop

TestTableMapReduce
- remove overrides of heartbeat and thread wake intervals

HADOOP-2396:

HMaster
- move check for null HRegionInfo before first attempt to dereference it.

HADOOP-2397:
- HMaster$BaseScanner.checkAssigned: don't try to split dead server's log if initial startup has completed.

HADOOP-2353:

HMsg
- change toString() to only output the region name rather than calling HRegionInfo.toString()

StaticTestEnvironment
- make logging a bit less verbose

TestHLog
- was writing to local file system and failing on Windows
