[jira] [Updated] (SPARK-6482) Remove synchronization of Hive Native
commands
[ https://issues.apache.org/jira/browse/SPARK-6482?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yin Huai updated SPARK-6482:
----------------------------
Target Version/s: 1.5.0 (was: 1.4.0)
> Remove synchronization of Hive Native commands
> ----------------------------------------------
>
> Key: SPARK-6482
> URL: https://issues.apache.org/jira/browse/SPARK-6482
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.3.0
> Reporter: David Ross
> Priority: Critical
>
> As discussed in https://issues.apache.org/jira/browse/SPARK-4908, concurrent hive native commands run into thread-safety issues with {{org.apache.hadoop.hive.ql.Driver}}.
> The quick-fix was to synchronize calls to {{runHive}}:
> https://github.com/apache/spark/commit/480bd1d2edd1de06af607b0cf3ff3c0b16089add
> However, if the hive native command is long-running, this can block subsequent queries if they have native dependencies.
