Review Comment:
this one is added for more explainatory exception in case of dropping
columns without cascade in case of parquet:
```
if (ParquetHiveSerDe.isParquetTable(table) &&
AlterTableUtils.isSchemaEvolutionEnabled(table, context.getConf()) &&
!desc.isCascade() && table.isPartitioned()) {
LOG.warn("Cannot drop column from a partitioned parquet table
without the CASCADE option");
throw new HiveException(ErrorMsg.DROP_COLUMN_UNCASCADED,
desc.getDbTableName());
}
```
