Can you translate your issue in english? also if it is not related to Java heap space, I would recommend you to create a new thread instead so that it is easy to track and others to contribute as well

Re: Map and Reduce Error: Java heap space

The default path is /opt/hadoop/dfs/nn

 

You can confirm this by Cloudera manager -> HDFS -> Configuration -> search for "dfs.namenode.name.dir"
