-----------------------------------------
Summary: HiveResult compatibility for DatasourceV2 command
Key: SPARK-31204
URL: https://issues.apache.org/jira/browse/SPARK-31204
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.0.0
Reporter: Juliusz Sompolski
HiveResult performs some compatibility matches and conversions for commands to
be compatible with Hive output, e.g.:
{code}
case ExecutedCommandExec(_: DescribeCommandBase) =>
// If it is a describe command for a Hive table, we want to have the
output format
// be similar with Hive.
...
// SHOW TABLES in Hive only output table names, while ours output database,
table name, isTemp.
case command @ ExecutedCommandExec(s: ShowTablesCommand) if !s.isExtended =>
{code}
It is needed for DatasourceV2 commands as well (eg. ShowTablesExec...).
