Let me also mention that the cluster contains one Namenode and one Datanode and this is the output of jps on each of them: Namenode: 6039 BSPMasterRunner 2068 NameNode 2727 TaskTracker 6272 Jps 2550 JobTracker 5989 ZooKeeperRunner 2241 DataNode 2424 SecondaryNameNode Datanode: 2303 DataNode 12864 GroomServerRunner 13126 Jps I will appreciate any help or suggestion to solve this issue. Thanks in advance. Regards, Vahe
