> PROBLEM
> Collector startup takes greater than 6mins even though the
> ApplicationHistoryServer is up in 2mins in secure cluster.
> Bug
> The collector startup script uses HBase shell to poll and check if the
> metrics schema is created. HBase shell takes a long time to respond in a
> secure environment without kinit.
> Fix
> Doing a "kinit" before starting up the metrics collector solves the
> performance issue
