no need to retry scan operation on the same server in the case of
RegionServerStoppedException
----------------------------------------------------------------------------------------------
Key: HBASE-4412
URL: https://issues.apache.org/jira/browse/HBASE-4412
Project: HBase
Issue Type: Bug
Reporter: Ming Ma
Assignee: Ming Ma
ScannerCallable.java doesn't retry on the same server in case of
NotServingRegionException.
if (ioe instanceof NotServingRegionException) {
// Throw a DNRE so that we break out of cycle of calling NSRE
// when what we need is to open scanner against new location.
// Attach NSRE to signal client that it needs to resetup scanner.
throw new DoNotRetryIOException("Reset scanner", ioe);
In the scenario when region server is in shutdown process,
RegionServerStoppedException will be thrown. ScannerCallable still retry. It
isn't necessary.
