> Currently, tajo provides column partition for partitioned table. But there is
> a lack in HCatalogStore. Tajo doesn't store a list of partitions for
> partitioned table in CatalogStore. But Hive store a list of partitions in
> HiveMetaStore. So, if you wrote partitioned table on Tajo, you must run msck
> repair function or add partition on Hive. I think that it is a very
> inefficient work. Thus, tajo need to repair partitioned directory list after
> writing partitioned table in HCatalgStore as follows:
> {code:xml}
> INSERT OVERWRITE INTO t1 SELECT l_orderkey FROM lineitem;
> ALTER TABLE lineitem ADD PARTITIONS;
> {code}
> For reference, "ADD PARTITIONS" just run on HCatalgStore.It doesn't run on
> another CatalogStore.
