---------------------------------
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}
