[jira] [Created] (FLINK-10346) MemoryStateBackend does not clean up
checkpoint directory
Till Rohrmann created FLINK-10346:
-------------------------------------
Summary: MemoryStateBackend does not clean up checkpoint directory
Key: FLINK-10346
URL: https://issues.apache.org/jira/browse/FLINK-10346
Project: Flink
Issue Type: Bug
Components: State Backends, Checkpointing
Affects Versions: 1.6.0, 1.5.3, 1.7.0
Reporter: Till Rohrmann
Fix For: 1.7.0
The {{StateBackendLoader}} creates a random subdirectory under {{HighAvailabilityOptions.HA_STORAGE_PATH}} for the {{MemoryStateBackend}} if no checkpointing directory has been specified (see {{StateBackendLoader.java:246}}). The problem is that this directory gets never removed after the {{MemoryStateBackend}} is closed. It is important to clean up these created directories.
