[I] Querying 2 tables across different broker tenants gives an ambiguous error message [pinot]
jadami10 opened a new issue, #11990:
URL: https://github.com/apache/pinot/issues/11990
We have table A on broker tenant A. Table B on broker tenant B. Trying to join these tables show `ProcessingException(errorCode:450, message:InternalError)`.
While it's expected this doesn't work (broker needs to know about both tables), the error message is extremely vague. I ended up having to search for it in the broker logs before confirming what the real issue was.

hmm. interesting. the error should have 5 lines of stack trace at least. is it only this without any messages attached?

@walterddr From what I can tell, the query should fail at `WorkerManager.assignWorkersToNonPartitionedLeafFragment()`: `Preconditions.checkState(!routingTableMap.isEmpty(), "Unable to find routing entries for table: %s", tableName);`

not really. this is only true if broker API is directly called. if it is called via controller API. the error message will be from
`PinotQueryResource.getMultiStageQueryResponse`:
```
QueryException.getException(QueryException.BROKER_REQUEST_SEND_ERROR, new Exception(
String.format("Unable to dispatch multistage query for tables: [%s]", tableNames))).toString();
```
b/c the return code is 450, it looks like it is directly hitting a broker and yes we are not returning proper error message here. good catch. will create a fix soon
