Haohui Mai updated FLINK-5931:
------------------------------
Description:
In order to use Flink in mission-critical environments, Flink must be available
even if the {{defaultFS}} is unavailable.
We have deployed HDFS in HA mode in our production environment. 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.
