   Thank you very much for your detailed description,
   1. The default distributed RPC port is 55560. I see that you have found the answer to this question.
   2. For cluster version testing, we generally use the support_ cluster branch[1] for testing, and the master is not used for the cluster version.

   > This means data is actually stored only under the node1 data folder.
   3. About node1's data folder size is getting bigger than node2 and node3. Because the default copy is 2 copies, and the data is partitioned according to storage group namee+ time, it is not possible to guarantee the same size of the data on the three nodes. You can use this tool[1] to look at data partitioning. 
   > Lots of "TTransportException: null" exceptions seen on logs.
   4. Yes, there are a large number of errors in the currently distributed version, but it does not affect the normal operation and can be ignored for the time being. However, we welcome to find out the essential cause of this problem.
