Hello, We have a hive metastore that is secured with kerberos. I need to access this from a mapreduce job but don't know how to authenticate. Due to our cluster setup I am currently looking at JDBC instead of HCatalog, but as far as I know, it is a bit of a hassle to do this. For example, how is the principal and the password/key used from within an MR job. Also how do I supply the jaas and kerberos configuration files together with the job? Can anyone give any pointers? I haven't found any clear examples of this on the web.
Best Regards Thomas
