Why are the dates in the log from 7/24/2014? Is this an old issue that hasn't been solved and you are reposting it, or is your clock incorrect? If your clock is incorrect, than you will have Kerberos issues since time is a big factor in determining the validity of the credentials. The clocks on the hosts need to be within 5 minutes of the host that contains the KDC, else bad things will happen. If this is an old issue and you are using HDP 2.1, then I assume you are using Ambari 1.6.x. In this version of Ambari, you must have set up Kerberos manually. Since there is a lot of room for error, you should go back and make sure you didn't miss a step or incorrect create a keytab file. Unless you create the keytab file for a particular principal using kadmin.local, the password for the account will get regenerated. This will cause issues if you create multiple keytab files for the same principal - the 2nd time you generate a keytab file, the 1st keytab file will become obsolete; the 3rd time you generate a keytab file, the 2nd keytab file will become obsolete, etc... Also, make sure all of the configs were set properly. By incorrectly setting a principal name or keytab file location, one or more services will fail to authenticate. Finally, check the ACLs on the keytab files to make sure that the relevant service(s) can read them. If a service is running as the local hdfs user, but the keytab file is only readable by root, than the service cannot read the keytab file and authentication will fail.
