Hi All,


Run hadoop fsck / will give you summary of current HDFS status
including some useful information :

 Minimally replicated blocks:   51224 (100.0 %)

 Under-replicated blocks:       0 (0.0 %)
 Mis-replicated blocks:         7 (0.013665469 %)
 Default replication factor:    3
 Average block replication:     3.0
 Missing replicas:              0 (0.0 %)
 Number of data-nodes:          83

Who can tell me the meaning of items? Thanks.
