'Not implemented by the DistributedFileSystem FileSystem implementation' error in Talend Big Data

'Not implemented by the DistributedFileSystem FileSystem implementation' error occassionally rears its head when debugging Talend Big Data jobs. This is a cryptic message that actually intends to convey that your job includes JARs from different versions of Hadoop in its classpath.

If you're using a standard version of Cloudera, MapR or Hortonworks Hadoop distributions in a Talend job, you will probably not encounter this error. However, if you have included additional JARs or are using a custom connector (a pack of JARs for a new or yet unsupported version of Hadoop), it is possible that you have included JARs that are of a different version than the Hadoop Cluster you're targeting, or JARs that are of a different versions.

To resolve the issue, check that the selected distribution and version of Hadoop on your Talend components match the set of JARs you're using. Also confirm that any JARs you're using match the target Hadoop distribution.
