----------------------------------

             Summary: The mapreduce.map.java.opts config in kylin_job_conf_inmem.xml overrides the krb5.conf config in Cluster
                 Key: KYLIN-3783
                 URL: https://issues.apache.org/jira/browse/KYLIN-3783
             Project: Kylin
          Issue Type: Bug
    Affects Versions: v2.5.2
         Environment: hadoop 2.7
            Reporter: yuzhang qiu


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

`
