Apache Spark reassigned SPARK-17810:
------------------------------------
Assignee: Sean Owen (was: Apache Spark)
> Default spark.sql.warehouse.dir is relative to local FS but can resolve as
> HDFS path
> ------------------------------------------------------------------------------------
>
> Key: SPARK-17810
> URL: https://issues.apache.org/jira/browse/SPARK-17810
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.1
> Reporter: Sean Owen
> Assignee: Sean Owen
>
> Following SPARK-15899 and
> https://github.com/apache/spark/pull/13868#discussion_r82252372 we have a
> slightly different problem.
> The change removed the {{file:}} scheme from the default
> {{spark.sql.warehouse.dir}} as part of its fix, though the path is still
> clearly intended to be a local FS path and defaults to "spark-warehouse" in
> the user's home dir. However when running on HDFS this path will be resolved
> as an HDFS path, where it almost surely doesn't exist.
> Although it can be fixed by overriding {{spark.sql.warehouse.dir}} to a path
> like "file:/tmp/spark-warehouse", or any valid HDFS path, this probably won't
> work on Windows (the original problem) and of course means the default fails
> to work for most HDFS use cases.
> There's a related problem here: the docs say the default should be
> spark-warehouse relative to the current working dir, not the user home dir.
> We can adjust that.
> PR coming shortly.
