Subject Re: hdfs2.7.3 not work with kerberos
Date Wed, 21 Sep 2016 09:55:40 GMT
I could see "Ticket cache: KEYRING:persistent:1004:1004" in your env.

May be KEYRING persistent cache setting is causing trouble, Kerberos
libraries to store the krb cache in a location and the Hadoop libraries
can't seem to access it.

Please refer these links,
