----------------------------------
Summary: 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: 2.1.3, 2.0.4, 2.2.0
Reporter: Allan Yang
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}
