             Summary: [RBF SBN] ConnectionManager should advance the client stateId for every request
                 Key: HDFS-16826
                 URL: https://issues.apache.org/jira/browse/HDFS-16826
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: ZanderXu
            Assignee: ZanderXu


ConnectionManager should advance the client stateId for every request whatever pool is null or not.

 

Bug Code as bellow:
{code:java}
// Create the pool if not created before
if (pool == null) {
  writeLock.lock();
  try {
    pool = this.pools.get(connectionId);
    if (pool == null) {
      pool = new ConnectionPool(
          this.conf, nnAddress, ugi, this.minSize, this.maxSize,
          this.minActiveRatio, protocol,
          new PoolAlignmentContext(this.routerStateIdContext, nsId));
      this.pools.put(connectionId, pool);
      this.connectionPoolToNamespaceMap.put(connectionId, nsId);
    }
    // BUG Here
    long clientStateId = RouterStateIdContext.getClientStateIdFromCurrentCall(nsId);
    pool.getPoolAlignmentContext().advanceClientStateId(clientStateId);
  } finally {
    writeLock.unlock();
  }
} {code}
