Launch distcp (or other MapReduce jobs) from outside the hadoop cluster, such as laptop

Hello,

 

I wonder what's the correct way of launching a distcp job (or any MapReduce job) from outside the hadoop cluster?

 

Basic info about my issue:

  • I can start a distcp from within the hadoop cluster just fine. Meaning that I can log into any hadoop node such as a yarn node and launch it with command

 

hadoop distcp -Dmapreduce.map.maxattempts=5 -update -m 50 -skipcrccheck -i -numListstatusThreads 30 -strategy dynamic <source folder> <destination folder>​

 

  • if I launch the distcp job from my laptop with the same command, I got this error:

I searched on the web for "java.io.DataInputStream.readFully(DataInputStream.java:197)" and haven't come across anything similar to my use case.

 

I also searched for "mapreduce job from outside cluster" and the closet that I can find is this: https://stackoverflow.com/questions/29268845/running-mapreduce-remotely/41238404

 

Any suggestion is much appreciated! Thanks!

Hi,

 

I just came across the same issue. And I want to consult that if this issue has been resolved.
