Description

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,
