Why are the changes needed?
In Kyuubi Batch v2 version, Batch Service creates
batchExecutorto submit a batch job. However, when openBatchSession fails, the executor dies and never recovers.This results in a jobs stuck at PENDING state and no executor to submit any jobs at INITIALIZED state.
This PR added error handling logic to handle openBatchSession.
This also fixes withUpdateCount call changes fromState to targetState.
How was this patch tested?
Tested in our environment, openBatchSession exceptions like connections per user or DB connection error no longer leaves jobs stuck at PENDING state. Instead all those jobs are labeled as ERROR.
Was this patch authored or co-authored using generative AI tooling?
