Riju Trivedi updated HIVE-11977:
--------------------------------
Description:
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.
