Gossiper.doStatusCheck() uses isMember() suspiciously
-----------------------------------------------------
Key: CASSANDRA-3895
URL: https://issues.apache.org/jira/browse/CASSANDRA-3895
Project: Cassandra
Issue Type: Sub-task
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).
