This is a similar issue with the permissions that people have
mentioned previously. Since I'm running whirr, I've been having
issues fixing this with advice from others.
I'm running whirr.cfg
file below:
whirr.service-name=hadoop
whirr.cluster-name=hd4node4
whirr.instance-templates=1 jt+nn,4 dn+tt
whirr.provider=ec2
whirr.location-id=us-east-1
whirr.hardware-id=t1.micro
whirr.identity=<>
whirr.credential=<>
whirr.private-key-file=${sys:user.home}/.ssh/id_rsa
whirr.public-key-file=${sys:user.home}/.ssh/id_rsa.pub
whirr.hadoop-install-runurl=cloudera/cdh/install
whirr.hadoop-configure-runurl=cloudera/cdh/post-configure
hadoop-hdfs.dfs.permissions=false
hadoop-mapreduce.mapreduce.jobtracker.staging.root.dir=/user
Is this last line the correct way to specify open permissions?
I've also tried "sudo -u hdfs hadoop fs -chmod 777 /". But that
doesnt seem to work either...
Anyone have an idea what my issue may be?
Appreciate the help!
Cheers,
Joris
