Usage of ORDER BY guarantees that a single file will be produced in directory {{{/tmp/hb_range_keys}}}. The filename is unknown, but it is necessary to reference the file by name later, so run a command such as the following to copy it to a specific name: {{{ - dfs -cp /tmp/hb_range_keys/* /tmp/hb_range_key_list + dfs -cp /tmp/hb_range_keys/* /tmp/hb_range_key_list; }}} = Prepare Staging Location = The sort is going to produce a lot of data, so make sure you have sufficient space in your HDFS cluster, and choose the location where the files will be staged.
