> * only really used in clidriver (via an infinite loop) [here|https://github.com/apache/hive/blob/master/cli/src/java/org/apache/hadoop/hive/cli/CliDriver.java#L307]
> * only 1 thing depends on the value of trycount; I think we can remove it  [GlobalLimitOptimizer|https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/optimizer/GlobalLimitOptimizer.java#L78]
> * there are a few loops which have pre-set trycount to 1 [example|https://github.com/apache/hive/blob/master/hcatalog/streaming/src/java/org/apache/hive/hcatalog/streaming/HiveEndPoint.java#L497]
> * other catches are exception repackagings
> I think it would be better to remove it.
> for more info:
> {code}
> git grep -C10 'catch.*CommandNeedRetryException'
> git grep -i gettrycount
> {code}
