> Components: Java
> Affects Versions: 1.5.6
> Reporter: Dongjoon Hyun
> Assignee: Owen O'Malley
> Priority: Major
>
> Unlike 1.5.5, ORC 1.5.6-rc1 seems to have a following issue which causes
> Apache Spark unit test failures.
> {code}
> $ build/sbt "sql/testOnly *.SQLQuerySuite"
> ...
> [info] Cause: java.lang.Throwable:
> [info] at
> org.apache.spark.DebugFilesystem$.addOpenStream(DebugFilesystem.scala:36)
> [info] at org.apache.spark.DebugFilesystem.open(DebugFilesystem.scala:70)
> [info] at org.apache.hadoop.fs.FileSystem.open(FileSystem.java:769)
> [info] at
> org.apache.orc.impl.ReaderImpl.extractFileTail(ReaderImpl.java:535)
> [info] at org.apache.orc.impl.ReaderImpl.<init>(ReaderImpl.java:368)
> [info] at org.apache.orc.OrcFile.createReader(OrcFile.java:343)
> {code}
> ORC-498 (ReaderImpl and RecordReaderImpl open separate file handles) seems to
> be the reason of this change.
