------------------------------------

I have copied hdfs-site.xml and core-site.xml files from aws instance and modified the files as to replace all the private IP with public IP of aws instance.

> Hi All,
> 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.
> *In logs I could see this:*
> 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:192)
> How can I resolve the UnresolvedAddressException issue,I have made an entry in hosts file of aws instance as :
> Private-IP Public DNS
> But this couldn't resolve my issue.
> Thanks,
