>                 Key: SPARK-8458
>                 URL: https://issues.apache.org/jira/browse/SPARK-8458
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 1.4.0
>            Reporter: Cheng Lian
>            Assignee: Cheng Lian

> To reproduce this issue, we first define {{fs.default.name}} in Hadoop {{core-site.xml}}:
> {noformat}
> <configuration>
>     ...
>     <property>
>         <name>fs.default.name</name>
>         <value>hdfs://localhost:9000</value>
>     </property>
>     ...
> </configuration>
> {noformat}
> Then execute the following Spark shell snippet:
> {code}
> sqlContext.range(0, 10).coalesce(1).write.mode("overwrite").format("orc").save("file:///tmp/foo")
> {code}
> The write job succeeds, but you can only find {{_SUCCESS}} under {{file:///tmp/foo}}. Data files are actually written to HDFS directory {{/tmp/foo/_temporary}} and left uncommitted.
> The reason is that, [this line|https://github.com/apache/spark/blob/9b2002722273f98e193ad6cd54c9626292ab27d1/sql/hive/src/main/scala/org/apache/spark/sql/hive/orc/OrcRelation.scala#L113] uses {{Path.toUri.getPath}} rather than {{Path.toString}} to pass the path string to {{OrcRecordWriter}} constructor, and this essentially strips the scheme part of the path.
