------------------------------------
sorry, i should be clear:
{code}
+ if (part != null) {
+
part.getTPartition().getSd().getSerdeInfo().setSerializationLib(serdeName);
+ if ((alterTbl.getProps() != null) && (alterTbl.getProps().size() > 0))
{
+ part.getTPartition().getSd().getSerdeInfo().getParameters().putAll(
+ alterTbl.getProps());
+ }
+ tbl.setFields(Hive.getFieldsFromDeserializer(tbl.getTableName(), tbl.
+ getDeserializer()));
+ } else {
+ tbl.setSerializationLib(alterTbl.getSerdeName());
+ if ((alterTbl.getProps() != null) && (alterTbl.getProps().size() > 0))
{
+ tbl.getTTable().getSd().getSerdeInfo().getParameters().putAll(
+ alterTbl.getProps());
+ }
+ tbl.setFields(Hive.getFieldsFromDeserializer(tbl.getTableName(), tbl.
+ getDeserializer()));
{code}
For the partition level, should not change the table object, and should change
the partition object.
