Large flow of log if the direct write Hadoop to Namenode load, so the merge before storage, you can each node log together into a file to write HDFs. It is synthesized on a regular basis and written to the HDFs. Let's look at the size of the log, 200G DNS log files, I compress to 18G, if you can use Awk Perl, of course, but the processing speed is certainly not distributed as the force. Hadoop Streaming principle Mapper and reducer ...
