---------------------------------
Summary: ADD PARTITIONS for HCatalogStore
Key: TAJO-1053
URL: https://issues.apache.org/jira/browse/TAJO-1053
Project: Tajo
Issue Type: Improvement
Components: catalog, operator/expression, parser
Reporter: Jaehwa Jung
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.
