EdColeman opened a new issue, #4559: URL: https://github.com/apache/accumulo/issues/4559
The scan servers write a lock with a path similar to: `/accumulo/[IID]/sservers/host:port/zlock#[LOCK_UUID]#[LOCK_SEQ]` The lock nodes are ephemeral and are removed if the server cannot renew the lease. However, the host:port part of the path is persistent, even across ZooKeeper restarts. The `.../sservers/host:port` path should be removed if a scan server is shutdown and there should be a cleaner thread that removes scan servers that do not have a lock if the scan server was not shutdown cleanly. There should be similar code that is used for teservers that maybe could be reused or adopted. This may apply to other services like external compactors, but not sure. -- This is an automated message from the Apache Git Service.
