Download data from a Hadoop on Azure cluster

So you’ve run a job on Hadoop on Azure, and now you want that data somewhere more useful, like in your Data Warehouse for some analytics. If the Hive ODBC Driver isn’t an option (perhaps because you used Pig), then FTP is the way – there isn’t a Javascript console fs.get() command available.

As described in my Upload data post, you need to use curl, and the command syntax is:

curl -k ftps://[cluster user name]:[password md5 hash]@[cluster name][path to data or specific file on HDFS] -o [local path name on your machine]

Happy downloading!

UPDATE: This functionality has now been disabled in HDInsight, see this thread from the MSDN Forum.
