Re: Re: hdfs2.7.3 not work with kerberos

[lk_hadoop]

Thank you Rakesh ,  Problem have been resolved.  
I should not config : default_ccache_name = KEYRING:persistent:%{uid} in 
krb5.conf. It's not work for hadoop.

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.

It's because of my jdk is 1.8 ?
