---------------------------------
Summary: Improve savepoint restore error messages
Key: FLINK-4413
URL: https://issues.apache.org/jira/browse/FLINK-4413
Project: Flink
Issue Type: Improvement
Components: State Backends, Checkpointing, Streaming
Affects Versions: 1.1.0
Reporter: Gyula Fora
Priority: Minor
Currently when savepoint restore fails due to some problems with parallelism or
the assigned uids the error messages contain all the job vertex id of the
problematic task.
This makes these kind of problems very difficult to debug for more complex
topologies.
I propose to add the user assigned task names to these error messages to make
this much easier for users.
