Subject [jira] [Created] (HIVE-2289) NumberFormatException with respect to _offsets when running a query with index

NumberFormatException with respect to _offsets when running a query with  index
-------------------------------------------------------------------------------

                 Key: HIVE-2289
                 URL: https://issues.apache.org/jira/browse/HIVE-2289
             Project: Hive
          Issue Type: Bug
          Components: Indexing
    Affects Versions: 0.7.0
         Environment: RedHat 5
            Reporter: siddharth ramanan


I am having a table named foo with columns origin, destination and information.

Steps I followed to create index named foosample for foo,

1)create index foosample on table foo(origin) as 'compact' with deferred rebuild;
2)alter index foosample on foo rebuild;
3)insert overwrite directory "/tmp/index_result" select '_bucketname','_offsets' from default__foo_foosample__
where origin='WAW';
4)set hive.index.compact.file=/tmp/index_result;
5)set hive.input.format=org.apache.hadoop.hive.ql.index.compact.HiveCompactIndexInputFormat;
6)select * from foo where origin='WAW';

Total MapReduce jobs = 1
Launching Job 1 out of 1
Number of reduce tasks is set to 0 since there's no reduce operator

Steps 2 and 3 ran a successful mapreduce job and also the table default__foo_foosample__ (index
table) has data with three columns origin, _bucketname and _offsets.

Thanks,
Siddharth
