Subject [jira] [Commented] (HIVE-2289) NumberFormatException with respect to _offsets when running a query with index
Date Mon, 18 Jul 2011 21:34:57 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2289?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13067317#comment-13067317
] 

Syed S. Albiz commented on HIVE-2289:
-------------------------------------

The column names in your step 3 need to be backticked, not quoted. Look at https://github.com/apache/hive/blob/trunk/ql/src/test/queries/clientpositive/index_auto.q
for an example query that runs properly.

> 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
