Christophe PRÉAUD created SPARK-6469:
----------------------------------------
Summary: Local directories configured for YARN are not used in
yarn-client mode
Key: SPARK-6469
URL: https://issues.apache.org/jira/browse/SPARK-6469
Project: Spark
Issue Type: Bug
Components: Spark Core
Reporter: Christophe PRÉAUD
Priority: Minor
According to the [Spark YARN doc
page|http://spark.apache.org/docs/latest/running-on-yarn.html#important-notes],
Spark executors will use the local directories configured for YARN, not
spark.local.dir which should be ignored.
If this works correctly in yarn-cluster mode, I've found out that it is not the
case in yarn-client mode.
The problem seems to originate in the method
[isRunningInYarnContainer|https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/util/Utils.scala#L686].
Indeed, I've checked with a simple application that the {{CONTAINER_ID}}
environment variable is correctly set in yarn-cluster mode (to something like
{{container_1426666761810_0151_01_000001}}, but not in yarn-client mode.
