We have a Cloudera cluster that I'm able to connect to from Hadoop Connect for Splunk, but getting timeouts.
The connection is successful from the command line terminal of our Splunk server, using the Hadoop CLI. I can get listings of Hadoop metadata using hadoop fs -ls hdfs://awetsa3uthdp03.cloud.our-company.org:8020. However, when using Hadoop Connect within Splunk, I get a timeout trying to connect:
Error connecting to /servicesNS/nobody/HadoopConnect/clusters/awetsa3uthdp03.cloud.our-company.org%3A8020: The read operation timed out
I'm using the latest version of the Splunk Hadoop Connector (1.2.3), and Splunk 6.2.
