-------------------------------
Summary: change checkpoint dir permission to 700 for security
reason
Key: FLINK-5818
URL: https://issues.apache.org/jira/browse/FLINK-5818
Project: Flink
Issue Type: Improvement
Components: Security, State Backends, Checkpointing
Reporter: Tao Wang
Now checkpoint directory is made w/o specified permission, so it is easy for
another user to delete or read files under it, which will cause restore failure
or information leak.
It's better to lower it down to 700.
