This is due to an incorrect temporary directory in the ambari.properties file. Once the (incorrect) temporary directory was manually created. The following error is observed:

27 Mar 2015 18:00:10,757  INFO

This was caused by incorrect permissions on /var/lib/ambari-server/tmp/.ambari_1427493565210-0.d/ip-10-99-165-62.ec2.internal/ where the directory was set to 600 (rw------) rather than 700 (rwx-----).

Solution

• Fix ambari.properties to have the correct server.tmp.dir value, which is /var/lib/ambari-server/data/tmp
• Make sure the directories in the created path has executable permissions for the user that Ambari executes as.
