Description

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 defaultfoo_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';

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,
