Peter Schuller resolved CASSANDRA-3895.
---------------------------------------
Resolution: Invalid
> Gossiper.doStatusCheck() uses isMember() suspiciously
> -----------------------------------------------------

> Key: CASSANDRA-3895
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3895
> Project: Cassandra
> Issue Type: Sub-task
> Components: Core
> Reporter: Peter Schuller
> Assignee: Peter Schuller
> Priority: Minor
>
> There is code for fat client removal and "old" endpoint (non-fat) removal
> which uses {{TokenMetadata.isMember()}} which only considers nodes that are
> joined (takes reads) in the cluster.
> aVeryLongTime is set to 3 days.
> I could very well be wrong, but the fat client identification code, the way I
> interpret it, is using isMember() to check basically whether a node is "part
> of the cluster" (in the most vague/broad sense) in order to differentiate a
> "real" node (part of the cluster) from just a fat client. But a node that is
> boot strapping is not a fat client, nor will be me a member according to
> isMember().
> I'm also a bit scared of, even in the case of there not being a fat client
> identification, simply forgetting an endpoint. It seems that an operator
> request should be relied upon to actively forget an endpoint (i.e., forced
> remove token).
