This post helps in cleanup of HDFS files older than a certain date(30days) using a shell script.

 today=`date +'%s'`  
 hdfs dfs -ls /file/Path/ | grep "^d" | while read line ; do  
 dir_date=$(echo ${line} | awk '{print $6}')  
 difference=$(( ( ${today} - $(date -d ${dir_date} +%s) ) / ( 24*60*60 ) ))  
 filePath=$(echo ${line} | awk '{print $8}')  
 if [ ${difference} -gt 30 ]; then  
   hdfs dfs -rm -r $filePath
