Subject [jira] [Created] (ACCUMULO-3574) preferCachedConnections=false is not respected
Date Tue, 10 Feb 2015 20:54:11 GMT
Josh Elser created ACCUMULO-3574:
------------------------------------

             Summary: preferCachedConnections=false is not respected
                 Key: ACCUMULO-3574
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3574
             Project: Accumulo
          Issue Type: Bug
          Components: rpc
    Affects Versions: 1.6.1, 1.6.0, 1.5.2, 1.5.1, 1.5.0
            Reporter: Josh Elser
            Assignee: Josh Elser
             Fix For: 1.5.3, 1.7.0, 1.6.3


{code}
  Pair<String,TTransport> getAnyTransport(List<ThriftTransportKey> servers, boolean
preferCachedConnection) throws TTransportException {
    ....
    if (!preferCachedConnection) {
      synchronized (this) {
        List<CachedConnection> cachedConnList = getCache().get(ttk);
        if (cachedConnList != null) {
          for (CachedConnection cachedConnection : cachedConnList) {
            if (!cachedConnection.isReserved()) {
              cachedConnection.setReserved(true);
              final String serverAddr = ttk.getServer().toString();
              log.trace("Using existing connection to {} timeout {}", serverAddr, ttk.getTimeout());
              return new Pair<String,TTransport>(serverAddr, cachedConnection.transport);
            }
          }
        }
      }
    }
{code}

It appears that ThriftTransportPool.getAnyTransport is returning a cache connection when the
caller requested that a new connection is returned instead of a cached one.
