Review request for Ambari, Dmytro Sen, Sumit Mohanty, and Sid Wagle.
Bugs: AMBARI-14078
https://issues.apache.org/jira/browse/AMBARI-14078
Repository: ambari
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
-----------------
NOTE : Some metrics collector startup script STDOUT echo statements (4-5) have
also been piped to the ambari-metrics-collector.out file to facilitate
debugging. Hence, the .out file will be appended to, across collector START
requests.
