Solutions

1. Check state-store DB health and permissions; deletion failures usually indicate DB corruption or I/O errors.
2. If the DB is corrupted, remove it and restart the NodeManager to rebuild recovery state.

When it happens

Trigger: Thrown by ShuffleHandler when removing a finished job's entry from the state store DB fails. Usually a transient DB error; if persistent, inspect the recovery store health on that node.

Common situations: See trigger scenarios.
