Yeah seems like its only working with 0.20.2 release at this point (203-205 upgraded the version, so that's the issue - compatibility broken). I repacked their jars with newer hadoop classes (DFSClient especially) and I think it works. I didn't test everything though.
Checking out their svn code and trying to build is turning out to be a nightmare (ant seems to have a load of deps, and no easy way of hadoop jar replacement?), so I'll pass on fixing their upstream stuff for a while. If anyone understands their build system better - do take a crack at it - they're completely open source :) On 21-Dec-2011, at 11:28 PM, Radim Kolar wrote: > i got following errror in log when using mucommander > > 2011-12-21 18:53:12,565 WARN org.apache.hadoop.ipc.Server: Incorrect header > or version mismatch from 88.102.**.**:11072 got version 3 expected version 4 > > what hdfs version you have? >
