Meta store remote addr is not defined

Error message

Meta store remote addr is not defined

What it means

A hard expect() panic in the meta store transport: meta_store_call was invoked, which requires forwarding to a remote meta store, but CUBESTORE_METASTORE_REMOTE_ADDRESS (the config's metastore_remote_address) is not set. The node is trying to act as a router proxy to a meta store it was never told about.

Solutions

1. Set the meta store remote address in the node's configuration when it must route to a remote meta store
2. Ensure only the designated router node forwards meta store calls, or run the meta store locally on this node
