----------------------------------------
Summary: NodeProbe (NodeTool) getEndpoint always return null
Key: CASSANDRA-10408
URL: https://issues.apache.org/jira/browse/CASSANDRA-10408
Project: Cassandra
Issue Type: Bug
Components: Tools
Reporter: amnon heiman
Priority: Minor
The NodeProbe getEndpoint implementation was changed to use the
getHostIdToEndpoint map with the host id.
There is a confusion between the keys and value. The search here should have
been a reverse lookup - in the map the host ids are the values not the keys.
The end result is that getEndpoint() will always return null, as a result
getDataCenter will be call the EndpointSnitchInfo getDatacenter with null,
which will be equivalent to call it with the loopback address, in that case
either fix the getEndpoint implementation, or drop it completely and use the
loopback address to begin with.
