----------------------------------

             Summary: Rename "recovery.mode" config key to "high-availability"
                 Key: FLINK-4253
                 URL: https://issues.apache.org/jira/browse/FLINK-4253
             Project: Flink
          Issue Type: Improvement
            Reporter: Ufuk Celebi


Currently, HA is configured via the following configuration keys:

{code}
recovery.mode: STANDALONE // No high availability (HA)
recovery.mode: ZOOKEEPER // HA
{code}

This could be more straight forward by simply renaming the key to {{high-availability}}. Furthermore, the term {{STANDALONE}} is overloaded. We already have standalone cluster mode.

{code}
high-availability: NONE // No HA
high-availability: ZOOKEEPER // HA via ZooKeeper
{code}

The {{recovery.mode}} configuration keys would have to be deprecated before completely removing them.
