Summary: Remove all local recovery files immediately when local
recovery fail
Key: FLINK-31969
URL: https://issues.apache.org/jira/browse/FLINK-31969
Project: Flink
Issue Type: Improvement
Components: Runtime / State Backends
Affects Versions: 1.18.0
Reporter: Yanfei Lei
In BackendRestorerProcedure, when local recovery fail, state backend will try
to recover from the remote state, at this time all local recovery files are
useless, they needs to wait until the next checkpoint to be cleared, deleting
local files immediately can better avoid file leakage, especially when the
local space is insufficient, deleting useless local recovery files can free up
space to download the remote state file.
