Maziar Mirzazad updated HADOOP-16996:
-------------------------------------
Description:
--
was:
With current hadoop client implementation, every single service need to add
UGI.loginFromKeyTab() before doing HDFS or M/R API calls.
To avoid that, we are proposing adding Keytab based login to hadoop client
library for Kerberized clusters with configurable default paths for Keytabs.
This improvement should avoid extra login tries in case a valid TGT is
available.
