Hi,

i setup a maprfs://<clustername> from my local machine (MAC OX)

**conf.set("fs.default.name", "maprfs://mycluster.com")<br/>
conf.set("mapred.job.tracker", "maprfs://mycluster.com")<br/>
conf.set("fs.maprfs.impl", "com.mapr.fs.MapRFileSystem")<br/>
conf.setInt("fs.mapr.mempool.size", 0)**

add the native library path on the eclipse project to
**../hadoop-0.20.2/lib/native/Mac_OS_X-x86_64-64**

The filesystem is success created<br/>
fileSystem = FileSystem.get("maprfs://mycluster.com", conf);


But when access to file sytem the the curren thread hangs.<br/>
Path path = new Path("/examplePath");<br/>
**fileSystem.exists(path)**

This error is loged on system err: (the ip address is masked by my)<br/>
