datetime - Hdfs file timestamp -


i want last_modification time of file on hdfs. checked hdfs shell guide did not relevant command available.

hadoop version 2.4.0. can suggest how can last_modification time of hdfs file?

thanks in advance

you can retrieve timestamp hadoop ls command , parse using awk.there pattern file/directory time stamp. file

permissions number_of_replicas userid groupid filesize modification_date modification_time filename  

and directory

permissions userid groupid modification_date modification_time dirname 

6th , 7th field file gives modification date , time. can use below sample retrieving information.

hadoop fs -ls /textfile | awk '{timestamp= $6  "  "  $7;print timestamp}' 

refer documentation ls command.
