> Key: KYLIN-1861
> URL: https://issues.apache.org/jira/browse/KYLIN-1861
> Project: Kylin
> Issue Type: Test
> Reporter: Shaofeng SHI
> Assignee: Shaofeng SHI
> Fix For: v1.5.3
>
>
> in conf/kylin_hive_conf.xml, it enables
> "hive.auto.convert.join.noconditionaltask", which is the optimization about
> converting common join into mapjoin based on the input file size, and give a
> big value (300000000, 300MB) to
> "hive.auto.convert.join.noconditionaltask.size". So if the memory of the
> mapper isn't enough, it will cause the error.
> To fix the error, user can reduce the
> "hive.auto.convert.join.noconditionaltask.size" in conf/kylin_hive_conf.xml,
> and then retry the job.
