    -- `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.
