Subject [jira] [Created] (SPARK-2814) HiveThriftServer throws NPE when executing native commands

---------------------------------

             Summary: HiveThriftServer throws NPE when executing native commands
                 Key: SPARK-2814
                 URL: https://issues.apache.org/jira/browse/SPARK-2814
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.1.0
            Reporter: Cheng Lian


After [PR #1686|https://github.com/apache/spark/pull/1686], {{HiveThriftServer2}} throws exception
when executing native commands.

The reason is that initialization of {{HiveContext.sessionState.out}} and {{HiveContext.sessionState.err}}
were made lazy, while {{HiveThriftServer2}} uses an overriden version of {{HiveContext}} that
doesn't know how to initialize these two streams.

Reproduction steps:

# Start HiveThriftServer2
# Connect to it via beeline
# Execute `set;`

Exception thrown:
{code}
