Description

I have used kylin-0.7.2 build cube and do some query, and I am trying kylin-1.0 in another hadoop cluster. I get this problem below in kylin-0.7.2 and kylin-1.0 :

Our hadoop cluster deals with authentication with kerberos, However, We find after submit a mapreduce job(the second step in building cube), kylin will send a http request to RM server and get the job status at regular intervals, But we always get errors here because kylin do nothing about kerberos. Finally , we do some change on source code and make it support kerberos authentication . attachment is my patch file..

I add a property named "kylin.job.status.with.kerberos" which means if we need do authentication with kerberos when getting status from RM, the default value is false.

It will be highly appreciated if you have some good idea or some suggestion. Thanks...
