Description

When trying to add a new OM to the already working cluster, the ozone om --bootstrap command fails with the following:

2022-12-22 17:23:19,457 [Listener at .../9862] ERROR om.OzoneManager: Terminating with exit status 1: OM(s) [om1[:9862],om3[:9862],om2[:9862]] do not have or have incorrect information of the bootstrapping OM. Update their ozone-site.xml before proceeding.

The failure happens during the config verification phase due to incorrect protocol description in org.apache.hadoop.ozone.om.protocolPB.OMAdminProtocolPB.
Instead of org.apache.hadoop.ozone.om.protocol.OMAdminProtocol it uses org.apache.hadoop.ozone.om.protocol.OzoneManagerMetadataProtocol which leads to a ClassNotFoundException on every checked node
