Issue

For some Cloudera/Hadoop WebHDFS configurations, the webhdfs interface was not usable for backups via Remote Archive Volumes.

Creating a Backup with these Remote Archive Volumes would yield the following error:

Remote volume error: The requested URL returned error: 400 Data upload requests must have content-type set to 'application/octet-stream'

 

Fix

Exasol now sets the HTTP header that is required to interact with these HDFS versions.
