From yesterday’s afternoon, my query progress in Apache IoTDB suddenly all get timeout. Error information is like DriverTask 20240226_053350_08273_3.2.0.0 is aborted by timeout. Since I use the cluster version of IoTDB, I checked the cluster settings first, and found that the confignode connection reported failure, like Failed to connect to ConfigNode TEndPoint(ip:tsdb3, port:10710) from DataNode TEndPoint(ip:tsdb1, port:6667), because the current node is not leader or not ready yet, will try again later. However, these error messages did not give me any idea of why this problem happened. Therefore, I want to ask if anyone can give me an idea on what configuration should I check now to narrow down the possible reason for this problem?
I seem to have encountered similar problems in previous tests. After troubleshooting, it seems that the configuration file has been changed. You can check the configuration file tsdbx and hosts in Apache IoTDB, and resume them to default settings if you change anything.
