Hi community, I'm new to the Spark community, and I'd like to discuss the first issue I'd like to work on. The problem is as follows:
When executing the following two commands in spark-shell: - CREATE TABLE default.test_table (test_col VARCHAR(10)); - ALTER TABLE default.test_table ALTER COLUMN test_col TYPE VARCHAR(25); The following error is reported: org.apache.spark.sql.AnalysisException: [NOT_SUPPORTED_CHANGE_COLUMN] ALTER TABLE ALTER/CHANGE COLUMN is not supported for changing `spark_catalog`.`default`.`test_table`'s column `test_col` with type "VARCHAR(10)" to `test_col` with type "VARCHAR(25)". SQLSTATE: 0A000; line 1 pos 0 Looking forward to everyone's replies! Best regards, Zhiwei Niu
