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.
