-----------------------------------
Hi [~hgadre],
Sounds great you're interested! To work on this, some basic background would be
helpful. Hadoop {{MiniKdc}} now mainly consists of {{SimpleKdcServer}} from
Kerby and in the SimpleKdcServer class you can access a handle {{KrbClient}}.
Using KrbClient you can do all kinds of supported logins and obtain a tgt; you
can also store the tgt in a ticket cache file; with the ticket cache then you
can do a Jaas login. Please go thru the stack and see if it helps. Note in
Kerby codebase there is a nice unit test named {{TicketCacheLoginTest}} where
all things link together. We could port the test to Hadoop based on Hadoop
MiniKdc.
> Ticket cache support for MiniKdc

> As discussed in HADOOP-9881, it would be good to support ticket cache
> generation utilizing MiniKdc, which can be used to test some Kerberos cases
> for UGI regarding user login via kinit or ticket cache. Currently it's not
> supported and this issue is to implement it.
