Hi Fawze, Sorry for my late respose and thanks for your reply. I have 2 hosts and already move Zookeeper Server, Hue Server, Hive Gateway and Hive Metastore Server successfully via Instance pages in Cloudera Manager. All Service Started and Status Good Health except HDFS. There is an Error from HDFS: Bad : 658 under replicated blocks in the cluster. 658 total blocks in the cluster. Percentage under replicated blocks: 100.00%. Critical threshold: 40.00% Result from : # $ hdfs fsck / -files -blocks -locations Status: HEALTHY Total size: 530731534 B Total dirs: 2293 Total files: 662 Total symlinks: 0 Total blocks (validated): 658 (avg. block size 806582 B) Minimally replicated blocks: 658 (100.0 %) Over-replicated blocks: 0 (0.0 %) Under-replicated blocks: 658 (100.0 %) Mis-replicated blocks: 0 (0.0 %) Default replication factor: 2 Average block replication: 1.0 Corrupt blocks: 0 Missing replicas: 658 (50.0 %) Number of data-nodes: 1 Number of racks: 1 FSCK ended at Tue Apr 18 07:16:43 UTC 2017 in 426 milliseconds The filesystem under path '/' is HEALTHY There is Missing replicas: 658 (50.0 %) My HDFS Replication Factor is set up to 2 and run hdfs dfs -setrep 2 /, but still not solved. Maybe you have solutions for this. Thanks
