> If a zero length file is in the top level directory housing an external avro
> table, all hive queries on the table fail.
> This issue is that org.apache.hadoop.hive.ql.io.avro.AvroGenericRecordReader
> creates a new org.apache.avro.file.DataFileReader and DataFileReader throws
> an exception when trying to read an empty file (because the empty file lacks
> the magic number marking it as avro).
> AvroGenericRecordReader should detect an empty file and then behave
> reasonably.
> Caused by: java.io.IOException: Not a data file.
