JoshRosen opened a new pull request, #36814: URL: https://github.com/apache/spark/pull/36814
### What changes were proposed in this pull request? This PR improves the error message that is thrown when trying to run `SHOW CREATE TABLE` on a Hive table with an unsupported serde. Currently this results in an error like ``` org.apache.spark.sql.AnalysisException: Failed to execute SHOW CREATE TABLE against table rcFileTable, which is created by Hive and uses the following unsupported serde configuration SERDE: org.apache.hadoop.hive.serde2.columnar.LazyBinaryColumnarSerDe INPUTFORMAT: org.apache.hadoop.hive.ql.io.RCFileInputFormat OUTPUTFORMAT: org.apache.hadoop.hive.ql.io.RCFileOutputFormat ``` This patch improves this error message by adding a suggestion to use `SHOW CREATE TABLE ... AS SERDE`: ``` org.apache.spark.sql.AnalysisException: Failed to execute SHOW CREATE TABLE against table rcFileTable, which is created by Hive and uses the following unsupported serde configuration SERDE: org.apache.hadoop.hive.serde2.columnar.LazyBinaryColumnarSerDe INPUTFORMAT: org.apache.hadoop.hive.ql.io.RCFileInputFormat OUTPUTFORMAT: org.apache.hadoop.hive.ql.io.RCFileOutputFormat Please use `SHOW CREATE TABLE rcFileTable AS SERDE` to show Hive DDL instead. ``` ### Why are the changes needed? The existing error message is confusing. ### Does this PR introduce _any_ user-facing change? Yes, it improves a user-facing error message. ### How was this patch tested? Manually tested with ``` CREATE TABLE rcFileTable(i INT) ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.columnar.LazyBinaryColumnarSerDe' STORED AS INPUTFORMAT 'org.apache.hadoop.hive.ql.io.RCFileInputFormat' OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.RCFileOutputFormat' SHOW CREATE TABLE rcFileTable ``` to trigger the error. -- This is an automated message from the Apache Git Service.
