Description

Original issue was HIVE-11303, seeing LimitExceededException when the client tries to get the counters for a completed job:

It looks like Limits.ensureInitialized() is defaulting to an empty configuration, resulting in COUNTERS_MAX being set to the default of 1200 (even though Hive's configuration specified tez.counters.max=16000).

Per sseth:

I think the Tez client does need to make this call to setup the Configuration correctly. We do this for the AM and the executing task - which is why it works. Could you please open a Tez jira for this ?
Also, Limits is making use of Configuration instead of TezConfiguration for default initialization, which implies changes to tez-site on the local node won't be picked up.
