In our > experience we have experienced performance degradations and downtime when the > HDFS cluster is being expanded or under maintenances. Under this case it is > desirable to deploy jobs through alternative filesystem (e.g., S3). > This jira is to track the improvements to Flink to enable Flink to continue > to operate even {{defaultFS}} is unavailable. -- This message was sent by Atlassian Jira (v8.3.4#803005)
