[I] Flink job stuck at the “INITIALIZING” stage when using RANGE distribution mode [iceberg]
hydrogenlee opened a new issue, #14079:
URL: https://github.com/apache/iceberg/issues/14079
### Apache Iceberg version
1.8.1
### Query engine
Flink
### Please describe the bug 🐞
Problem:
When running a flink job with **RANGE** distribution mode, after several cycles of running the job for a while, stopping with a savepoint, and restarting from that savepoint, the range shuffle operator stuck at the “**INITIALIZING**” status without any error or warn logs, while all other operators successfully transition to the RUNNING state.
Steps to Reproduce:
1. Run a job in range distribution mode.
2. Stop with savepoint.
3. Restart from the savepoint.
4. Repeat steps 1–3 multiple times.
5. Eventually, after a restart, the job gets stuck in the INITIALIZING stage.
The hot thread of range-shuffle operator is:
