New script to export from HBase so that we could in theory reimport into HBase. I've not tried the reimport out, but I followed instructions to export and I got a non-zero output file, so I am assuming it worked. 2. Committing today's new crawls in crawledNode4.tar. Each crawled site's folder inside it now includes a file called part-m-* that is the exported Hbase on that node VM. 3. Updated hdfs related GS_README.txt with instructions on viewing the contents of a table in HBase and a link on exporting/importing from HBase. 4. Minor changes like the tar files shouldn't be called tar.gz.
