Daryn Sharp commented on HADOOP-9299:
-------------------------------------
I should add I also spoke to [~atm] about the kerberos entangled quite awhile
ago. He said they had an issue where the static initialization of the kerberos
classes were triggering dns discovery of the KDCs which overwhelmed the dns
server. I think the problem was even a bit more severe.
I'm trying to re-familiarize myself with the code and what I thought needed to
be done w/o breaking anything.

> This is submitting a mapreduce job via Oozie 3.3.1. The reason I think this
> is a Hadoop issue rather than the oozie one is because when I hack
> /etc/krb5.conf to be:
> {noformat}
> [libdefaults]
> ticket_lifetime = 600
> default_realm = LOCALHOST
> default_tkt_enctypes = des3-hmac-sha1 des-cbc-crc
> default_tgs_enctypes = des3-hmac-sha1 des-cbc-crc
> [realms]
> LOCALHOST = {
> kdc = localhost:88
> default_domain = .local
> }
> [domain_realm]
> .local = LOCALHOST
> [logging]
> kdc = FILE:/var/log/krb5kdc.log
> admin_server = FILE:/var/log/kadmin.log
> default = FILE:/var/log/krb5lib.log
> {noformat}
> The issue goes away.
> Now, once again -- the kerberos auth is NOT configured for Hadoop, hence it
> should NOT pay attention to /etc/krb5.conf to begin with.
