I have an Process group which has various component.The last step is to put the data to HDFS using PutHDFS. I see this error in the HDFS step, can't figure out why this is happening. Here is the Screenshot to the same.
Your filename starts with a dot, I wonder if that is a hidden or temp file and perhaps can't be accessed by the Hadoop client. If that's not the case, is some other app deleting the contents of the data folder while you're trying to write to it? A Google search for that error implies that after/while a file is written, it has been deleted, then something tries to access it (NiFi's Hadoop client in this case).
