----------------------------------
Summary: Hive fails on zero length sequence files
Key: HIVE-12607
URL: https://issues.apache.org/jira/browse/HIVE-12607
Project: Hive
Issue Type: Bug
Components: Serializers/Deserializers
Affects Versions: 1.2.1
Reporter: Chaoyu Tang
Assignee: Chaoyu Tang
Flume will, at times, generate zero length sequence files which cause the Hive
query failure.
To reproduce the issue:
{code}
> create external table test (id string)
partitioned by (system string,date string)
STORED AS SEQUENCEFILE
LOCATION '/user/me/test';
hadoop fs -mkdir /user/me/test/logs
hadoop fs -mkdir /user/me/test/logs/date=2014
hadoop fs -touchz /user/me/test/logs/date=2014/a.txt
hive
-> ALTER TABLE test ADD PARTITION (system = 'logs',date='2014') location
'/user/me/test/logs/date=2014';
-> select * from test t1,test t2 where t1.id = t2.id;
{code}
