> This direct SQL call fails for every {{getPartitions}} call and then falls
> back to ORM.
> The query which fails is
> {code}
> select
> PARTITIONS.PART_ID, SDS.SD_ID, SDS.CD_ID,
> SERDES.SERDE_ID, PARTITIONS.CREATE_TIME,
> PARTITIONS.LAST_ACCESS_TIME, SDS.INPUT_FORMAT, SDS.IS_COMPRESSED,
> SDS.IS_STOREDASSUBDIRECTORIES, SDS.LOCATION, SDS.NUM_BUCKETS,
> SDS.OUTPUT_FORMAT, SERDES.NAME, 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 ( ? ) order by PART_NAME asc;
> {code}
> By looking at the source {{MetaStoreDirectSql.java}}, the third column in the
> query ( SDS.CD_ID), the column descriptor ID, is null, which triggers the
> exception. This exception is not thrown from the ORM layer since it is more
> forgiving to the null column descriptor. See {{ObjectStore.java:1197}}
> {code}
> List<MFieldSchema> mFieldSchemas = msd.getCD() == null ? null :
> msd.getCD().getCols();
> {code}
> I verified that this exception gets triggered in the first place when we add
> a new partition without setting column level schemas for the partition, using
> the MetaStoreClient API. This exception does not occur when adding partitions
> using the CLI
> I see two ways to solve the issue.
> 1. Make the MetaStoreClient API more strict and not allow creating partition
> without having column level schemas set. (This could break clients which use
> the MetaStoreclient API)
> 2. Make the Direct SQL code path and the ORM code path more consistent, where
> the Direct SQL does not fail on null column descriptor ID.
> I feel 2 is more safer and easier to fix.
