(Updated Dec. 13, 2016, 10:38 p.m.)
Review request for Ambari, Alejandro Fernandez, Nate Cole, and Tim Thorpe.
Bugs: AMBARI-19156
https://issues.apache.org/jira/browse/AMBARI-19156
Repository: ambari
Description
-------
Install packages step (before RU/EU) fails with err "Cannot enumerate services"
if the current stack has services that have been removed in the new stack. For
example, mystack-1.0 has Spark, but mystakc-2.0 only has Spark2, where Spark's
metainfo.xml in mystack-2.0 has the <deleted>true</deleted> section.
Workaround is to remove Spark before attempting the install packages.
The error is below:
02 Dec 2016 12:53:43,928 ERROR [ambari-client-thread-27]
BaseManagementHandler:61 - Caught a system exception while attempting to create
a resource: Cannot enumerate services
org.apache.ambari.server.controller.spi.SystemException: Cannot enumerate
services

Testing
-------
1. unit tests
2. patched a cluster with the fixes, update new stack to remove Spark ( leaving
only Spark 2), run Install Packages, verify it didn't fail with the "Cannot
enumerate services" error.
Thanks,
Di Li
