> While looking at root_dir_external_table.q failure, which is doing a query on an external table located at root ('/'), I noticed that latest Hadoop2 CombineFileInputFormat returns split representing empty directories (like '/Users'), which leads to failure in Hive's CombineFileRecordReader as it tries to open the directory for processing.
> Tried with an external table in a normal HDFS directory, and it also returns the same error.  Looks like a real bug.
