Status: Ready to Commit (was: Patch Available)
> streaming failure during bootstrap makes new node into inconsistent state
> -------------------------------------------------------------------------
>
> Key: CASSANDRA-14525
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14525
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Jaydeepkumar Chovatia
> Assignee: Jaydeepkumar Chovatia
> Priority: Major
> Fix For: 4.0, 2.2.x, 3.0.x
>
>
> If bootstrap fails for newly joining node (most common reason is due to
> streaming failure) then Cassandra state remains in {{joining}} state which is
> fine but Cassandra also enables Native transport which makes overall state
> inconsistent. This further creates NullPointer exception if auth is enabled
> on the new node, please find reproducible steps here:
> For example if bootstrap fails due to streaming errors like
