> Consider the following scenario:
> set hive.optimize.bucketmapjoin = true;
> set hive.optimize.bucketmapjoin.sortedmerge = true;
> set hive.input.format =
> org.apache.hadoop.hive.ql.io.BucketizedHiveInputFormat;
> set hive.enforce.bucketing=true;
> set hive.enforce.sorting=true;
> set hive.exec.reducers.max = 1;
> set hive.merge.mapfiles=false;
> set hive.merge.mapredfiles=false;
> -- Create two bucketed and sorted tables
> CREATE TABLE test_table1 (key INT, value STRING) PARTITIONED BY (ds STRING)
> CLUSTERED BY (key) SORTED BY (key) INTO 2 BUCKETS;
> CREATE TABLE test_table2 (key INT, value STRING) PARTITIONED BY (ds STRING)
> CLUSTERED BY (key) SORTED BY (key) INTO 2 BUCKETS;
> FROM src
> INSERT OVERWRITE TABLE test_table1 PARTITION (ds = '1') SELECT *;
> -- Insert data into the bucketed table by selecting from another bucketed
> table
> -- This should be a map-only operation
> INSERT OVERWRITE TABLE test_table2 PARTITION (ds = '1')
> SELECT a.key, a.value FROM test_table1 a WHERE a.ds = '1';
> We should not need a reducer to perform the above operation.
