> 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...
