Fixed Re: On CDH2, (Cloudera EC2) No valid local directories in property: mapred.local.dir
Saptarshi Guha 2010-02-19, 22:49
As a follow up, this is not peculiar to my programs but hadoop ones too:
I started the cluster as (using Fedora AMI and c1.medium)

hadoop-ec2 launch-cluster --env REPO=testing --env HADOOP_VERSION=0.20 test2 1

and error is [1]

But it works(and so do my programs) if I launch a cluster with e.g. 4
nodes as opposed to 1.

Regards
