[Solved] Nebula executes Algorithm Error: Error scanvertexresultiterator: get storage client error

The problem indicates that the storage client cannot be connected.

Solution:

Execute on the nebula console

show hosts;

Since the default is 127.0.0.1, the storage client gets the storage address through the metad service when connecting to the nebula storage, so the storage address obtained in the spark connector is 127.0.0.1:9779, which is wrong.

Therefore, you can change the default address to the real address.
