----------------------------------
Summary: RU: Alter service check order
Key: AMBARI-12863
URL: https://issues.apache.org/jira/browse/AMBARI-12863
Project: Ambari
Issue Type: Bug
Components: ambari-server
Reporter: Nate Cole
Assignee: Nate Cole
Priority: Critical
Fix For: 2.1.2
HBase service check failed consistently because the HBase Master died as it was
trying to write the WAL and could not find enough good datanodes. The service
check for HBase was run before the service check for HDFS. There may be a
situation in which we're not giving enough time for all the DN's to come up
before the HBase service check is being performed, and if it would make more
sense to service check HDFS before we service check HBase due to dependencies.
With that said it feels like the RU service check order should be:
* ZooKeeper
* HDFS
* YARN
* Everything else
