>
> the config "hive.cluster.delegation.token.gc-interval" is set as long
> duration, 1 hour. This created some issues in a heavy loaded cluster in which
> the tokens may not be cleaned up fast enough and the cleaner thread may fail
> to clean the tokens. This may cause issues like eating too much space or LLAP
> startup failures, or slow system startup.
> If this hive.cluster.delegation.token.gc-interval” is reduced from 1 hour to
> a relatively shorter period such as 15 mins, then the zookeeper tokens will
> be cleaned more timely and mitigate these issues.
