Jayush Luniya commented on AMBARI-9117:
---------------------------------------
This is caused because of incorrect cleanup during upgrade. If you check
/var/lib/ambari-server/resources/stacks/HDP/2.0.6/services after upgrade you
will see empty package directory for each service. This results in an empty
archive.zip to be created which is replicated to the ambari-agent cache as an
empty folder.
Because of the empty packageDir, stack inheritence will return the packageDir
for HDP2.2 HDFS to be
/var/lib/ambari-agent/cache/resources/stacks/HDP/2.0.6/services/HDFS/package
instead of
var/lib/ambari-agent/cache/resources/common-services/HDFS/2.1.0.2.0/package
because of which you are seeing this failure.

/var/lib/ambari-server/resources/stacks/HDP/2.0.6/services/FLUME
root@c6401 FLUME# ls -l package/
total 0
-rwxr-xr-x 1 root root 0 Jan 9 03:02 archive.zip
Workaround:
If you delete the empty package folders (i.e. folders with empty archive.zip as
well) from /var/lib/ambari-server/resources/stacks/HDP and
/var/lib/ambari-agent/cache/stacks/HDP and then start the ambari-server and
ambari-agent the issue should resolve itself. I will look at how we can add
this cleanup.

> Issue Type: Task
> Components: ambari-agent, ambari-server
> Affects Versions: 2.0.0

> After upgrading Ambari from 1.7.0 to 2.0.0, the Dashboard does not come up
> because the agent host check fails since the common services scripts are not
> copied to /var/lib/ambari-agent/cache/
> This could be related to AMBARI-8695
> STR:
> 1. Install Ambari 1.7.0 on a single node cluster, and add HDP 2.2 with HDFS
> and ZK
> 2. Upgrade Ambari to 2.0.0
> Stop all services
