Description

In our cluster, we use kerberos for authorization, and config `-Djava.security.krb5.conf` in `mapreduce.map.java.opts`. But the default configuration in kylin_job_conf_inmem.xml is `-Xmx2700m -XX:OnOutOfMemoryError='kill -9 %p'`, which will overrides the krb5 config when the cubing algorithm is *inmem*. Then, we got `Caused by: KrbException: Cannot locate default realm
