> Key: HUDI-4079
> URL: https://issues.apache.org/jira/browse/HUDI-4079
> Project: Apache Hudi
> Issue Type: Improvement
> Reporter: Jin Xing
> Assignee: Jin Xing
> Priority: Minor
> Labels: pull-request-available
> Fix For: 0.11.1, 0.12.0
>
>
> When creating table like below with a 'comment' and check by "show create
> table", the comment is not shown
>
> {code:java}
> create table test(
> id int,
> name string,
> price double,
> ts long
> ) using hudi
> comment "This is a simple hudi table"
> tblproperties (
> primaryKey = 'id',
> preCombineField = 'ts'
> ){code}
>
> The cause is as below:
> # Current hudi & spark3 invokes ShowCreateTableExec when "show create ..."
> # ShowCreateTableExec checks table property of 'comment' for result
> # Spark HiveClientImpl hides property of 'comment', but set it to
> Catalog#comment when returning a CatalogTable
> (https://github.com/apache/spark/blob/master/sql/hive/src/main/scala/org/apache/spark/sql/hive/client/HiveClientImpl.scala#L487)
