Tao Wang updated SPARK-13935:
-----------------------------
Affects Version/s: 1.6.0
1.6.1
> Other clients' connection hang up when someone do huge load
> -----------------------------------------------------------
>
> Key: SPARK-13935
> URL: https://issues.apache.org/jira/browse/SPARK-13935
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.5.0, 1.5.2, 1.6.0, 1.6.1
> Reporter: Tao Wang
> Priority: Critical
>
> We run a sql like "insert overwrite table store_returns partition
> (sr_returned_date) select xxxxxx" using beeline then it will block other
> beeline connection while invoke the Hive method via
> "ClientWrapper.loadDynamicPartitions".
> The reason is that "withHiveState" will lock "clientLoader". Sadly when a new
> client comes, it will invoke "setConf" methods which is also sychronized with
> "clientLoader".
> So the problem is that if the first sql took very long time to run, then all
> other client could not connect to thrift server successfully.
> We tested on release 1.5.1. not sure if latest release has same issue.
