Review request for Ambari, Andrew Onischuk and Robert Levas.


Bugs: AMBARI-10691
    https://issues.apache.org/jira/browse/AMBARI-10691


Repository: ambari


Description
-------

Problem:

I ran Ambari 1.7 to install HDP 2.2 on a VM after changing all the /var/log, /var/run, /hadoop
references form defaults to instead be under some other dir. I am encountering a number of
Ambari failures which I needed help on.
After the install wizard error out I also noticed:
HS2 does not stay up. From the logs I see below error
org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException):
Permission denied: user=hive, access=WRITE, inode="/":hdfs:hdfs:drwxr-xr-x

Solution:

When hive uses a custom hive.exec.scratchdir path on the Hadoop Filesystem, it automatically
tries to create said path at start and it will fail to do so as it does not have the required
permissions.
Ambari will create said custom folder if needed and set the appropiate permissions.
