I'm currently running Ignite as a Hadoop accelerator via IGFS backed by a secondary HDFS store. The cluster currently functions as expected, but I'm seeing some anomalies in the metrics reported by Ignite. In particular, on a fresh cluster, when a node restarts (exits and rejoins), the igfs-meta TX commit rate jumps up from ~0/sec to ~4/sec for all the nodes in the cluster. This rate increases as additional nodes leave/join. From the looks of it, it seems to be correlated to the TX rollback rate. Is there a reason why this might be the case?
