> LOAD DATA LOCAL INPATH '../../data/files/lineitem.txt' OVERWRITE INTO TABLE aa;
> CREATE INDEX aa_lshipdate_idx ON TABLE aa(l_shipdate) AS 'org.apache.hadoop.hive.ql.index.AggregateIndexHandler'
WITH DEFERRED REBUILD IDXPROPERTIES("AGGREGATES"="count(l_shipdate)");
> ALTER INDEX aa_lshipdate_idx ON aa REBUILD;
> show tables;
> explain select l_shipdate, count(l_shipdate)
> from aa
> group by l_shipdate;
> {code}
> The problem is that, we create an index table default_aa_lshipdate_idx, (default is the
database name) and it comes after the table aa. Then, it first drop aa, which will drop default_aa_lshipdate_idx
as well as it is related to aa. It will not find the table default_aa_lshipdate_idx when it
tries to drop it again, which will throw an exception.
