HADOOP-2407 Keeping MapFile.Reader open is expensive: Part 2


HADOOP-2392, HADOOP-2324:


- initialChore() now returns boolean


- 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.


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


- remove overrides of heartbeat and thread wake intervals



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


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



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


- make logging a bit less verbose


- was writing to local file system and failing on Windows

HADOOP-2401. Only the current leaseholder can abandon a block for
