-----------------------------------------
Assignee: Alex Khakhlyuk
> Improve noHandlerFoundForExtension error message
> ------------------------------------------------
>
> Key: SPARK-55373
> URL: https://issues.apache.org/jira/browse/SPARK-55373
> Project: Spark
> Issue Type: Bug
> Components: Connect
> Affects Versions: 4.1.1
> Reporter: Alex Khakhlyuk
> Assignee: Alex Khakhlyuk
> Priority: Major
> Labels: pull-request-available
>
> Currently, Spark Connect Planner supports extension fields for Relation,
> Command, Expression protos. Extensions are processed through handlers. If a
> handler is not available for a given extension type, the planner will throw
> this error:
> {code:java}
> org.apache.spark.sql.connect.common.InvalidPlanInput: [INTERNAL_ERROR] No
> handler found for extension SQLSTATE: XX000 {code}
> This error is not informative enough when debugging. I propose adding
> extension proto type url to the error message which will make it clear which
> extension is missing
> {code:java}
> org.apache.spark.sql.connect.common.InvalidPlanInput: [INTERNAL_ERROR] No
> handler found for extension type:
> type.googleapis.com/google.protobuf.StringValue SQLSTATE: XX000 {code}
