----------------------------------
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
`
