Question

I\'m getting the following error when attempting to write to HDFS as part of my multi-threaded application

could only be replicated to 0 nodes instead of min         


        

Answer 1

I had the same error, re-starting hdfs services solved this issue. ie re-started NameNode and DataNode services.
