描述

Similarly to https://github.com/confluentinc/ksql/issues/7772, this error message is not super helpful to understand what's going on:

https://github.com/confluentinc/ksql/blob/1a1297ab59db0af416a924d4135b93dcc5003561/ksqldb-engine/src/main/java/io/confluent/ksql/physical/pull/HARouting.java#L244-L246

We should include more information to help expose what's going on, such as which partitions failed and which hosts were attempted.
