> 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.
