Release Note

The patch replaces -namenode option with -fs for specifying the remote name node against which the benchmark is running. Before this patch, if '-namenode' was not given, the benchmark would run in standalone mode, ignoring the 'fs.defaultFS' in config file even if it's remote. With this patch, the benchmark, as other tools, will rely on the 'fs.defaultFS' config, which is overridable by -fs command option, to run standalone mode or remote mode.

Description

HDFS-7847 introduced a new option -namenode, which is intended to point the benchmark to a remote NameNode. It should use a standard generic option -fs instead, which is routinely used to specify NameNode URI in shell commands.
