Description

Mounts the Hadoop configurations, either as a pre-defined config map, or a local configuration directory on the Pod.

We plan to provide two options for the users to mount custom Hadoop configurations:

• option 1: specify an existing ConfigMap that contains custom Hadoop Configurations, one can share a single ConfigMap for more than one Flink clusters.
• option 2: create a dedicated ConfigMap containing Hadoop Configurations loaded from the local directory specified by the HADOOP_CONF_DIR or HADOOP_HOME environment, then bind that ConfigMap to the lifecycle of the new Flink cluster.
