Subject [jira] [Commented] (SPARK-15401) Spark Thrift server creates empty directories in tmp directory
Date Thu, 19 May 2016 09:36:12 GMT

    [ https://issues.apache.org/jira/browse/SPARK-15401?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15290792#comment-15290792
] 

Christophe Préaud commented on SPARK-15401:
-------------------------------------------

The thrift server above is launched on a YARN cluster (hence in yarn-client mode).
The tmp directory on the driver has been set to "/opt/kookel/data/spark-tmp" using the two
properties below:
spark.local.dir=/opt/kookel/data/spark-tmp
spark.driver.extraJavaOptions=-Djava.io.tmpdir=/opt/kookel/data/spark-tmp

But the problem was the same when it was set to the default /tmp

>    Affects Versions: 1.6.1

> Each connection to the Spark thrift server (e.g. using beeline) creates two empty directories
in the tmp directory which are never removed:
> cd <tmp directory>
> ls -ltd *_resources | wc -l && /opt/spark/bin/beeline -u jdbc:hive2://dc1-kdp-prod-hadoop-00.prod.dc1.kelkoo.net:10000
-n kookel -e '!quit' && ls -ltd *_resources | wc -l
> 9080
> Connecting to jdbc:hive2://dc1-kdp-prod-hadoop-00.prod.dc1.kelkoo.net:10000
> Connected to: Spark SQL (version 1.6.1)
> Driver: Spark Project Core (version 1.6.1)
> Transaction isolation: TRANSACTION_REPEATABLE_READ
> Closing: 0: jdbc:hive2://dc1-kdp-prod-hadoop-00.prod.dc1.kelkoo.net:10000
> Beeline version 1.6.1 by Apache Hive
> 9082
> Those directories accumulates over time and are not removed:
> ls -ld *_resources | wc -l
> 9064
> And they are indeed empty:
> find *_resources -type f | wc -l
> 0
