jdwoody opened a new issue #1069: TServer in inconsistent state is never removed
URL: https://github.com/apache/accumulo/issues/1069
 
 
   Recently observed a TServer on a node with hardware issues. The instance was alive, but not functioning. The Master polls all tservers via gatherTableInformation and this server would repeatedly throw a TTransportException on connect. After 3 failures, an attempt is made to halt the server, however, if a TTransportException is thrown, the exception is ignored and the server is assumed to be down.
   [Link to ignored Exception](https://github.com/apache/accumulo/blob/master/server/master/src/main/java/org/apache/accumulo/master/Master.java#L1230)
   
   Propose that the Zookeeper lock be removed by the master on this failure or possibly provide an option for the behavior. `LiveTServerSet.remove` could be an option.
