Hello @baabdullah ,   The error indicates that your DataNode is down. Could you please confirm if that's the scenario?    Error: could only be written to 0 of the 1 minReplication nodes. There are 0 datanode(s) running and 0 node(s) are excluded in this operation. Could you please check the data node logs to identify the exact issue?
