How to copy files recursive from HDFS to a local folder?
The simple way to copy a folder from HDFS to a local folder is like this:
su hdfs -c 'hadoop fs -copyToLocal /hdp /tmp'
In the example above, we copy the hdp folder from HDFS to /tmp/local_folder
But we have a more complicated case. Let’s say under /hdp ( hdfs ), we have
subfolders:
/hdp/folder1
/hdp/folder2
/hdp/folder3/folder_a
.
.
.
And in each subfolder we have files.
In that case, how to copy recursively only the files under /hdp to the local dir /tmp/local_folder?
