I don't think its ready for production use yet, and nobody has -yet- gone beyond looking at what it would take to switch Hadoop over to it. latest intel parts, as Hadoop already does for HDFS encryption), and broader protocol support. You may be interested to hear of Apache Kerby, an ongoing project to have a pure Java Kerberos Domain Controller and, importantly for production Hadoop -a modern Kerberos client library, with CPU-acceleration of encryption when available (i.e. If we stay with the Oracle libraries, we're stuck with whatever they implement, which, as you've noticed, is pretty limited and out of date. internal classes to get some stuff done, and that tends to break across major (and sometimes minor) releases. That's pretty problematic, because we have to delve into the private com.sun. Hadoop uses the Kerberos libraries that come with the JVM.

"I'm sure HDO engineering team must be looking into this for a solution, since KEYRING is the future for kerberos cache and the stuff you can do with it like keylist and etc." If you still see KEYRING PERSISTENT, kill all the running sessions of the user having the problem and restart SSSD thanks for this Logout and log in again - destroy the previous tickets and you should have something like "Ticket cache: FILE:/tmp/krb5cc_" in your klist output. To solve the errors you can comment out the "default_ccache_name=KEYRING." on krb.conf or change it to "default_ccache_name = FILE:/tmp/krb5cc_%"

KEYRING persistent cache setting works with many applications however not with HADOOP Cluster, I'm sure HDO engineering team must be looking into this for a solution, since KEYRING is the future for kerberos cache and the stuff you can do with it like keylist and etc. You will still be able to get the tickets but will have GSSException error on Cluster.

One of our clients have RedHat IDM (supported version of freeIpa) and when you install sssd along with krb5 by IDM the default cache setting is 'KEYRING' than 'File' I came across a Kerberos cache issue and wanted to share and possible have more ideas.
