HDFS under replicated blocks

under replicated blocks 
to solve: 
find no copy of the Block: 
HDFS fsck / | grep ' Under replicated ' | awk -F ' : '  ' {1} Print $ ' >> / tmp / under_replicated_files 
then repair cycle: 
for hdfsfile in `CAT / tmp / under_replicated_files`; do echo " Fixing $ hdfsfile: " ; Hadoop FS -setrep . 3 $ hdfsfile; DONE 
output as follows:
