------------------------------
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.

# One node crash, the whole cluster has running issue and exception.
