Option to change storage class for listener pvc

[rajarshp]

Hi Team,

We are seeing an issue when using Stackable HDFS, where it is using listener PVC to store the namenode address. But current this is using a local storage class which is tied up with a particular node.

Now if there is patching or cluster upgrade which will remove these nodes and assigning a new node, then these PVCs are not able to find the node and going in invalid state when it is impacting the namenode and they are coming up.

For now the only work around is to manually delete the PVC and then recreate them by the operator, but is there an option to change this listeners.stackable.tech storage class to anything else ?
