HowTo: Debugging/Running localmode on YARN ?
Hello all,
I just discovered that with 23 shims the localmode is driven by
SET mapreduce.framework.name=local;
not by the traditional SET mapred.job.tracker=local; Has anyone put together a how-to for debugging/running localmode on Yarn, like Thejas had for classic Hadoop at http://hadoop-pig-hive-thejas.blogspot.ie/2013/04/running-hive-in-local-mode.html ?
My specific issue is that on localmode I get error launching the job due to missing HDFS file:
java.io.FileNotFoundException: File does not exist: hdfs://sandbox.hortonworks.com:8020/usr/lib/hcatalog/share/hcatalog/hcatalog-core.jar

Changing SET fs.default.name=file:///tmp; 'solves' the error, but I'm a bit confused why using the (valid and running!) HDFS does not work. It seems to me that the HDFS resource in question is just a concat of the default FS with a localpath, not a valid HDFS name...
Thanks,

Posted by Vinod Kumar Vavilapalli <vi...@apache.org>.
Local mapreduce job-runner was never supported/tested with HDFS though it could logically work.
Thanks,
