> 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.
