TestScannerTimeout fails occasionally
-------------------------------------
Key: HBASE-3666
URL: https://issues.apache.org/jira/browse/HBASE-3666
Project: HBase
Issue Type: Bug
Affects Versions: 0.90.1
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Fix For: 0.90.2
If I loop TestScannerTimeout, it eventually fails with:
org.apache.hadoop.hbase.regionserver.LeaseException:
org.apache.hadoop.hbase.regionserver.LeaseException: lease
'-4526340287831625207' does not exist

org.apache.hadoop.hbase.regionserver.Leases.cancelLease(Leases.java:209)

org.apache.hadoop.hbase.regionserver.HRegionServer.next(HRegionServer.java:1816)

I think the issue is a race where at the top of the function, the scanner does
exist, but by the time it gets to cancelLease, it has timed out.
