title: Is there an alternative for hadoop -getmerge?
body: <p>I was trying to merge 80 GB files in a cluster using hadoop get merge ,</p>
  <p>but as hadoop get merge has the property of copying the files from hdfs to local file system i have to copy to local and then copyFromLocal to hdfs again ,</p>
  <blockquote>
  <p>hadoop fs -<strong>getmerge</strong> hdfs:///path_in_hdfs/* ./local_path</p>
  <p>hadoop fs <strong>-copyFromLocal</strong> ./local_path hdfs://Destination_hdfs_Path/</p>
  </blockquote>
  <p>My problem here is The datanode local is less than 80 GB,</p>
  <p>I need to know is there an alternative to -getmerge where merge happens directly from HDFS to HDFS</p>
  <p>I tried hadoop -cat also but it is not working..</p>
