If after you get up and running you would like to run blur against a hdfs instance then obviously you will need hdfs running. And the storage uri will change to something like: "hdfs://hostname:port/blur/tables/table-dir". > > 4) The QuickStart at this link http://wiki.apache.org/blur/QuickStart is > outdated. > Ok, is it because of #5 or is there another problem with the document?

However I'm for setting one up for next week on Wednesday, perhaps 4:30 is a little early? 5 or 5:30?
