Shaofeng SHI commented on KYLIN-3783:
-------------------------------------
The default configuration file may not consider all cases. You can modify the
kylin_job_conf_inmem.xml manually to match your environment need, the file in
conf/ folder is for that case.
> 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
> Priority: Minor
>
> 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
> `
