>             Project: HBase
>          Issue Type: Bug
>          Components: integration tests
>            Reporter: Josh Elser
>            Assignee: Josh Elser
>            Priority: Trivial
>             Fix For: 2.0.0, 1.4.0, 1.3.2, 1.5.0, 1.2.7, 1.1.13
>         Attachments: HBASE-18679.001.patch, HBASE-18679.002.patch
> YARN has a configuration limit to the number of counters that a job can create (to avoid
some bad job from DDOS'ing the service).
> When running ITBLL, we ran into this limit due to the default configuration rather low
at the time. When YARN notices that the counter limit has been exceeded, it nulls out the
Counters object obtained by the Job.
> Presently in ITBLL, we have a few places where we (reasonably ;)) assume that the Counters
object would be non-null. Can easily fix this with a null-check.
