I am using Talend Big Data Sandbox 6.3. I have a MapReduce job that attempts to read data from an Oracle server. When I run the job, it throws an Unknown Host Exception with the Oracle server. I did docker exec -it cluster1_cdh580_1 /bin/bash and tried pinging from the container. Seems like it doesn't recognise any URL, not even google.
I would appreciate some help.
Could you please give us more information about the Unknown Host Exception with the Oracle server? You can successfully connect to your oracle server through client without using talend tool? Your MapReduce job setting screenshots will be preferred.
