Description

In some cases, FetchHDFS's default "HDFS Filename" value (which is ${path}/${filename}) might end up with double separator in the evaluated value. For example if the ${path} is the root, then the value will start with "//". In most cases this cause no issue, but there are some scenarios it might behave unexpectedly. Like for example: if the storage is backed with S3 or Azure, this path leads to an error.
