setrep
Changes the replication factor of a file.
If the specified path points to a directory, the command recursively changes the replication factor of all files under the specified directory. The EC files will be ignored when executing this command.
Returns 0 on success and -1 on error.
The usage is as follows:
$ hadoop fs -setrep [-R] [-w] <numReplicas> <path>-w |
Requests the command to wait for the replication to complete. This can potentially take a very long time |
-R |
Accepted for the backward compatibility. It has no effect |
Example:
$ hadoop fs -setrep -w 3 /user/hadoop/dir1
