Log file is uploaded.
AFAIK the problem is that RatisPipelineUtils.createPipeline connected to a non-leader node.
But it's not clear for me how is it possible. According to the log (attached) the leader election continued after the NonLeaderException. It can be just the sign that one datanode was missing from the pipeline...
