[jira] [Commented] (SPARK-13983) HiveThriftServer2 can not get
"--hiveconf" or ''--hivevar" variables since 1.6 version (both
multi-session and single session)
[ https://issues.apache.org/jira/browse/SPARK-13983?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15200328#comment-15200328 ]

------------------------------------
[~lian cheng] Could you help to look at this one?

> Key: SPARK-13983
> URL: https://issues.apache.org/jira/browse/SPARK-13983
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.6.0, 1.6.1
> Environment: ubuntu, spark 1.6.0 standalone, spark 1.6.1 standalone
> (tried spark branch-1.6 snapshot as well)
> Reporter: Teng Qiu
>
> HiveThriftServer2 should be able to get "\--hiveconf" or ''\-\-hivevar" variables from JDBC client, either from command line parameter of beeline, such as
> {{beeline --hiveconf hive.stats.autogather=false --hivevar db_name=default}}
> or from JDBC connection string, like
> {{jdbc:hive2://localhost:10000?hive.stats.autogather=false#db_name=default}}
> this worked in spark version 1.5.x, but after upgraded to 1.6, it doesn't work.
> to reproduce this issue, try to connect to HiveThriftServer2 with beeline:
> {code}
> bin/beeline -u jdbc:hive2://localhost:10000 \
> --hiveconf hive.stats.autogather=false \
> --hivevar db_name=default
> {code}
> or
> {code}
> bin/beeline -u jdbc:hive2://localhost:10000?hive.stats.autogather=false#db_name=default
> {code}
> will get following results:
> {code}
> 0: jdbc:hive2://localhost:10000> set hive.stats.autogather;
> +-----------------------+--------------+--+
> | key | value |
> +-----------------------+--------------+--+
> | hive.stats.autogather | <undefined> |
> +-----------------------+--------------+--+
> 1 row selected (0.01 seconds)
> 0: jdbc:hive2://localhost:10000> use ${db_name};
> Error: org.apache.spark.sql.AnalysisException: cannot recognize input near '$' '{' 'db_name' in switch database statement; line 1 pos 4 (state=,code=0)
> {code}
> -
> but this bug does not affect current versions of spark-sql CLI, following commands works:
> {code}
> bin/spark-sql --master local[2] \
> --hiveconf hive.stats.autogather=false \
> --hivevar db_name=default
> spark-sql> set hive.stats.autogather;
> hive.stats.autogather false
> Time taken: 1.037 seconds, Fetched 1 row(s)
> spark-sql> use ${db_name};
> OK
> Time taken: 1.697 seconds
> {code}
> so I think it may caused by this change: https://github.com/apache/spark/pull/8909 ( [SPARK-10810] [SPARK-10902] [SQL] Improve session management in SQL )
> perhaps by calling {{hiveContext.newSession}}, the variables from {{sessionConf}} were not loaded into the new session? (https://github.com/apache/spark/pull/8909/files#diff-8f8b7f4172e8a07ff20a4dbbbcc57b1dR69)
