> "hive.lock.numretries" Is Misleading
> ------------------------------------
>
> Key: HIVE-19378
> URL: https://issues.apache.org/jira/browse/HIVE-19378
> Project: Hive
> Issue Type: Improvement
> Components: HiveServer2
> Affects Versions: 3.0.0, 2.4.0
> Reporter: BELUGA BEHR
> Assignee: Alice Fan
> Priority: Minor
> Attachments: HIVE-19378.1.patch
>
>
> Configuration 'hive.lock.numretries' is confusing. It's not actually a
> 'retry' count, it's the total number of attempt to try:
>
> {code:java|title=ZooKeeperHiveLockManager.java}
> do {
> lastException = null;
> tryNum++;
> try {
> if (tryNum > 1) {
> Thread.sleep(sleepTime);
> prepareRetry();
> }
> ret = lockPrimitive(key, mode, keepAlive, parentCreated,
> conflictingLocks);
> ...
> } while (tryNum < numRetriesForLock);
> {code}
> So, from this code you can see that on the first loop, {{tryNum}} is set to
> 1, in which case, if the configuration num*retries* is set to 1, there will
> be one attempt total. With a *retry* value of 1, I would assume one initial
> attempt and one additional retry. Please change to:
> {code}
> while (tryNum <= numRetriesForLock);
> {code}
