Subject [jira] [Updated] (AMBARI-2130) Use modified dependencies if a stack contains an HCFS service (Hadoop Compatible File System)
Date Fri, 07 Jun 2013 17:14:20 GMT

     [ https://issues.apache.org/jira/browse/AMBARI-2130?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Trevor McKay updated AMBARI-2130:
---------------------------------

    Attachment: hcfs_deps_test.patch

This patch (hcfs_deps_test.patch) adds a unit test for dynamic RoleCommandOrder objects (RCOs).

The essential logic generates alternate dependencies within an RCO if a cluster has the HCFS
service defined.  Currently, the only stack that defines the HCFS service is HDP-1.3.1.

The test proves that dependencies for clusters with the HDFS service are equal for stack versions
HDP-1.3.0 and HDP-1.3.1, but that the dependencies for a cluster differ when the HCFS service
is used on stack version HDP-1.3.1.
