--------------------------------
Summary: [state] Avoid memory stateBackend to create arbitrary
folders under HA path when no checkpoint path configured
Key: FLINK-11107
URL: https://issues.apache.org/jira/browse/FLINK-11107
Project: Flink
Issue Type: Bug
Components: State Backends, Checkpointing
Affects Versions: 1.7.0, 1.6.2
Reporter: Yun Tang
Assignee: Yun Tang
Fix For: 1.6.3, 1.7.1
Currently, memory state-backend would create a folder named with random UUID
under HA directory if no checkpoint path ever configured. (the code logic
locates within {{StateBackendLoader#fromApplicationOrConfigOrDefault}})
However, the default memory state-backend would not only be created on JM side,
but also on each task manager's side, which means many folders with random UUID
would be created under HA directory. It would result in exception like:
{noformat}
The directory item limit of /tmp/flink/ha is exceeded: limit=1048576
items=1048576{noformat}
If this happens, no new jobs could be submitted only if we do not clean up
those directories manually.
