------------------------------

             Summary: Cluster version not available
                 Key: IOTDB-1041
                 URL: https://issues.apache.org/jira/browse/IOTDB-1041
             Project: Apache IoTDB
          Issue Type: Bug
          Components: Core/Cluster
            Reporter: Liu Yue


Following are some issues we encountered when try to use cluster version of IoTDB:
 # There is no cluster version bin package available. And the master branch does not support cluster, we need re-compile cluster_new branch.
 # While compiling cluster_new branch, it needs to access Amazon Cloud. We have to bypass by proxy in private network environment.
 # After compiling cluster_new branch and tried, the cluster cannot start.

By analyzing code, the nodeIdentifier option has no implementation, thus failed to start at first.

 # When one node failed and down, the whole cluster cannot start.

As following code lines, "canEstablishCluster" is true only when all node started successfully.

 # The logic of checking cluster starting has some problem.

If "consistentNum == totalSeedNum" then check pass, but there probably cannot get all nods information at this time point.
