Hi Team,
I have recently started exploring Apache nifi to implement in our upcoming projects. The issue is: I have nifi installed on my windows machine to transfer the data from oracle database to aws instance hdfs layer by using putHDFS. files are transferred to hdfs with 0 Bytes of memory.(Attached the snapshot for reference) I was able to place files using putsftp in aws instance without any issue,but failed to do it in hdfs layer. In logs I could see this: <logs> WARN [Thread-5441] org.apache.hadoop.hdfs.DFSClient DataStreamer Exception java.nio.channels.UnresolvedAddressException: null at sun.nio.ch.Net.checkAddress(Unknown Source) at sun.nio.ch.SocketChannelImpl.connect(Unknown Source) at org.apache.hadoop.net.SocketIOWithTimeout.connect(SocketIOWithTimeout.java:1 92) </logs> Procedure followed: I have copied the hdfs-site.xml and core-site.xml from aws instance and replaced all private hostname with public hostname as I cannot communicate with private DNS,then I provided those two files as inputs to apache nifi configuration. The hdfs layer has full permissions to write to it. Could someone help on this as I have struck at this point from longtime, made many changes in hosts file for resolving hostname issue.
