## High Availability Mode
-- `recovery.mode`: (Default 'standalone') Defines the recovery mode used
for the cluster execution. Currently, Flink supports the 'standalone' mode
where only a single JobManager runs and no JobManager state is checkpointed.
The high availability mode 'zookeeper' supports the execution of multiple
JobManagers and JobManager state checkpointing. Among the group of JobManagers,
ZooKeeper elects one of them as the leader which is responsible for the cluster
execution. In case of a JobManager failure, a standby JobManager will be
elected as the new leader and is given the last checkpointed JobManager state.
In order to use the 'zookeeper' mode, it is mandatory to also define the
`recovery.zookeeper.quorum` configuration value.

named 'recovery.mode' and the default config was 'standalone'.

Oh yes. Will change them too.

> 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.
