Yeap ! I have restart all and reinstall all and it works. :) But i have another questions : - I have seen that Master runs with his RegionServer and the others in the cluster. But it's possible to run Master only and the others RegionServer in the cluster? - Is there a great difference between the HDFS and a folder like /tmp to stock the HBase file (table, etc..) ?
