Subject Trouble running Giraph on YARN / Hadoop 2.5.2
Date Tue, 10 Mar 2015 03:39:44 GMT
Folks:

I'm trying to run the basic ShortestPaths example using Giraph 1.1 on
Hadoop 2.5.2.  I'm running in actual cluster model (eg, not
psuedo-distributed) and I can run standard mapreduce jobs OK.   But
when I try to run the Giraph example, it seems to hang unless I set

    -ca giraph.SplitMasterWorker=false

and correspondingly set number of workers to 1.  But this kinda
defeats the point of running on a cluster, no?   OTOH, if I run
without disabling SplitMasterWorker, I get this error:

    When using LocalJobRunner, you cannot run in split master / worker mode
    since there is only 1 task at a time!

which suggests that Girpah is defaulting to local mode.  One report I
read suggested fixing this by adding

   -ca mapred.job.tracker=10.0.0.12:5431

to the Girpah command line, but on Hadoop 2.5.2 with YARN, there is no
JobTracker on port 5431, if I understand correctly.  Anyway, if I do
add that bit, the job **tries** to run, but seems to hang without ever
finishing.  Here's the complete command line, and the job output
follows:
