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:
