How to overwrite the existing files using hadoop fs -copyToLocal command

Question

Is there any way we can overwrite existing files, while coping from HDFS using:

hadoop fs -copyToLocal  
         


        

Answer 1

You could try this :

bin/hadoop fs -rm /path_of_the_file | grep "0" | bin/hadoop fs -put ~/input_path /output_path

Answer 2

You can first delete, then write.

hadoop fs -rmr <path> removes everything under given path in hdfs including the path itself

rm -rf <path> removes in local file system.

Make sure that there is no other file in the directory.
