Hi @hippagun It wont work. though its ORC hive will be able to differentiate the columns based on the delimiter which you have specified during the table creation. So no matter whether you re-create it it wont work. There are two option which you can do now: 1) Create another external table with the additional columns. Write a simple query to load the records from old to the new table specifying null the newly added columns. Once it is done drop the old table. Going forward you can make use of this table. It will be suitable for ORC 2) The other way is, If the schema of the table changes frequently then its better to go with avro table as the schema changes can be handled easily. You have to follow the above step just for the first time. But whenever there is any changes in the schema in future then you need to alter the schema file and nothing else is needed. You can refer to this Link to get the understanding of the handling the schema changes in avro file. Hope it helps!! ... View more
