[jira] [Updated] (FLINK-27108) State cache clean up doesn't work as expected

     [ https://issues.apache.org/jira/browse/FLINK-27108?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dian Fu updated FLINK-27108:
----------------------------
    Description: The test case test_session_window_late_merge failed when working on FLINK-26190. After digging into this problem, I found that the reason should be that the logic to determine [whether a key & namespace exists in state cache is wrong|https://github.com/apache/flink/blob/master/flink-python/pyflink/fn_execution/state_impl.py#L1183] is wrong. It causes the state cache isn't clean up when it becomes invalidate.   (was: The test case test_session_window_late_merge failed when working on FLINK-26190.
