Hadoop Flags: Reviewed
> LeaseException in Scan should be retired
> ----------------------------------------
>
> Key: HBASE-22047
> URL: https://issues.apache.org/jira/browse/HBASE-22047
> Project: HBase
> Issue Type: Bug
> Affects Versions: 2.2.0, 2.0.4, 2.1.3
> Reporter: Allan Yang
> Assignee: Igor Rudenko
> Priority: Major
> Fix For: 3.0.0, 2.3.0, 2.1.5, 2.2.1
>
>
> We should retry LeaseException just like other exceptions like
> OutOfOrderScannerNextException and UnknownScannerException
> Code in ClientScanner：
> {code:java}
> if ((cause != null && cause instanceof NotServingRegionException) ||
> (cause != null && cause instanceof RegionServerStoppedException) ||
> e instanceof OutOfOrderScannerNextException || e instanceof
> UnknownScannerException ||
> e instanceof ScannerResetException) {
> // Pass. It is easier writing the if loop test as list of what is
> allowed rather than
> // as a list of what is not allowed... so if in here, it means we do
> not throw.
> if (retriesLeft <= 0) {
> throw e; // no more retries
> }
> {code}
