Description

MR and HDFS use the Configuration.getTrimmedStrings API for local directory lists, but in a few places also use Configuration.getLocalPath. The former API trims whitespace around each entry in the list, but the latter doesn't. This can cause some subtle problems - the latter API should be fixed to also trim the directory names.
