Drat. Thanks. tjake on "How to "register" the cfs:// scheme" http://www.datastax.com/support-forums/topic/how-to-register-the-cfs-scheme#post-125 Fri, 27 May 2011 19:21:43 +0000 tjake 125@http://www.datastax.com/support-forums/ Hi Matt, Assuming you have setup your classpath correctly you need the following in your core-site.xml <property> <name>fs.cfs.impl</name> <value>org.apache.cassandra.hadoop.fs.CassandraFileSystem</value> </property> matt on "How to "register" the cfs:// scheme" http://www.datastax.com/support-forums/topic/how-to-register-the-cfs-scheme#post-124 Fri, 27 May 2011 19:18:51 +0000 matt 124@http://www.datastax.com/support-forums/ I have a web application that I need to convince to read files out of cfs. The code calls org.apache.hadoop.fs.Path.getFileSystem() on an instance of a path object initialized with: cfs:///root/subdir/ But when I call that, I get: java.io.IOException: No FileSystem for scheme: cfs at org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:1307) at org.apache.hadoop.fs.FileSystem.access$100(FileSystem.java:65) at org.apache.hadoop.fs.FileSystem$Cache.get(FileSystem.java:1328) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:226) at org.apache.hadoop.fs.Path.getFileSystem(Path.java:187) I know the hadoop classes are being loaded from the jars bundled with brisk, but I'm not sure how to convince this method call that my path is valid with cfs:// in front of it. If I drop that, I just get a reference to a local filesystem, which coincidentally exists. Thoughts?
