             Summary: Hive metastore query too long when select * on table with large number of partitions
                 Key: HIVE-7999
                 URL: https://issues.apache.org/jira/browse/HIVE-7999
             Project: Hive
          Issue Type: Bug
          Components: Metastore
            Reporter: Chu Tong




When it comes to selecting * on a Hive table with large number of partitions, a query like this:

SELECT PARTITIONS.PART_ID, SDS.SD_ID, SDS.CD_ID, SERDES.SERDE_ID, PARTITIONS.CREATE_TIME, ... SERDES.SLIB from PARTITIONS LEFT OUTER JOIN SDS ON PARTITIONS.SD_ID = SDS.SD_ID LEFT OUTER JOIN SERDES ON SDS.SERDE_ID = SERDES.SERDE_ID where PART_ID in (1,2,3,4 ... 10000000 ...

is generated and executed on metastore, however, due the query lists all the partitions in it, SQL server is unable to compile/execute such a long query and causing the whole query to fail.
