[jira] [Updated] (HBASE-3666) TestScannerTimeout fails occasionally
[ https://issues.apache.org/jira/browse/HBASE-3666?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
andylee updated HBASE-3666:
---------------------------
Description:
LeaseExceptionIf I loop TestScannerTimeout, it eventually fails with:
org.apache.hadoop.hbase.regionserver.LeaseException: org.apache.hadoop.hbase.regionserver.LeaseException: lease '-4526340287831625207' does not exist
at org.apache.hadoop.hbase.regionserver.Leases.cancelLease(Leases.java:209)
at org.apache.hadoop.hbase.regionserver.HRegionServer.next(HRegionServer.java:1816)
...
at org.apache.hadoop.hbase.client.ScannerCallable.call(ScannerCallable.java:83)
at org.apache.hadoop.hbase.client.ScannerCallable.call(ScannerCallable.java:38)
at org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation.getRegionServerWithRetries(HConnectionManager.java:1003)
at org.apache.hadoop.hbase.client.HTable$ClientScanner.next(HTable.java:1103)
at org.apache.hadoop.hbase.client.HTable$ClientScanner.next(HTable.java:1175)
at org.apache.hadoop.hbase.client.TestScannerTimeout.test2772(TestScannerTimeout.java:133)
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.
