Subject [jira] [Created] (HIVE-17991) Remove CommandNeedRetryException
Date Mon, 06 Nov 2017 18:55:00 GMT
Zoltan Haindrich created HIVE-17991:

             Summary: Remove CommandNeedRetryException
                 Key: HIVE-17991
             Project: Hive
          Issue Type: Improvement
            Reporter: Zoltan Haindrich

* only really used in clidriver (via an infinite loop) [here|]
* only 1 thing depends on the value of trycount; I think we can remove it  [GlobalLimitOptimizer|]
* there are a few loops which have pre-set trycount to 1 [example|]
* other catches are exception repackagings

I think it would be better to remove it.

for more info:

git grep -C10 'catch.*CommandNeedRetryException'
git grep -i gettrycount
