Hi there!
Have you checked your hadoop config files ($HADOOP_HOME/conf)?
especially $HADOOP_HOME/conf/*core-site.xml*
and $HADOOP_HOME/conf/*mapred-site.xml*
And you might also want to check in your ~/*.ssh/config* - if you have one.
Hope that helps :)

Hello everybody. I'm executing a BFS algoritm on giraph, and i hit
with this error. I searched for uppercase letters in the following files:
/etc/*hostname*
/etc/*hosts*
/usr/local/hadoop/zookeeper/conf/*zoo.cfg* (contains zookeeper
configuration)
/usr/local/hadoop/etc/hadoop/*masters*
/usr/local/hadoop/etc/hadoop/*slaves*
In my entire cluster (one master and two child nodes)*. *I couldn't
find a single uppercase letter in those configurations files. My nodes
have this names:
*hdnode01
*
*hadoop100
*
*hadoop101*
Is there any file left that i should check in order to detect where is
my mistake? This problem can be related with any other configuration
problem?
Thanks Alessio for your contribution, you help me a lot writing this,
and you could help me a lot more if you help me here !! :D
Bye!

Pd: Numbers aren't considered uppercase letters... right?

Hello everybody
I’m here to share my experience with the error “Worker failed during input
split (currently not supported)”. I have seen several help requests in this
mailing list asking for help for this kind of situation, so I’d like to share
my experience: it could help at least some of you.
This is the incriminated error log:
> barrierOnWorkerList: Missing chosen workers [Worker(hostname=01hw789772,
> MRtaskID=1, port=30001)] on superstep -1
> 2014-11-25 20:55:13,590 ERROR org.apache.giraph.master.MasterThread:
> masterThread: Master algorithm failed with IllegalStateException
> java.lang.IllegalStateException: coordinateVertexInputSplits: Worker
failed
> during input split (currently not supported)
In my case the error was related to Giraph-904 bug
(https://issues.apache.org/jira/browse/GIRAPH-904). In fact, in
the first line the system logs that there are missing workers (and
my hostname was written in only lowercase chars, while my former
hostname had both lowercase and uppercase chars). I managed to
solve my issue by using a hostname made up by only lowercase chars.
Hope this helps someone: in the meantime, I’ll report that this
issue is still open (and not fixed) in Jira.
