Description

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
