Summary: hive fails when hive.exec.mode.local.auto=true
Key: HIVE-9575
URL: https://issues.apache.org/jira/browse/HIVE-9575
Project: Hive
Issue Type: Bug
Affects Versions: 0.14.0
Environment: CentOS 6.5
Reporter: David Watzke
Hello, we're using hive 0.14.0 with cloudera 5.3 and a problem occurs when we
set hive.exec.mode.local.auto=true for running a small query. The query fails
with this error:
java.lang.NullPointerException

but if we also set mapred.job.tracker=local, then it works fine.
Having to manually set mapred.job.tracker to 'local' kind of defies the purpose
of the local.auto feature.
