When setting up the namenode, some of the commands that we run are:
hadoop fs -mkdir /tmp
hadoop fs -chmod -R 1777 /tmp
This has worked for previous CDH releases of Hadoop.
We recently upgraded our test cluster to CDH 4.1 and the chmod no longer works.
sudo -u hdfs hadoop fs -chmod -R 1777 /tmp
chmod: chmod : mode '1777' does not match the expected pattern.
sudo -u hdfs hadoop fs -chmod -R +t /tmp
chmod: chmod : mode '+t' does not match the expected pattern.
This disagrees with the docs here: https://ccp.cloudera.com/display/CDH4DOC/Deploying+MapReduce+v1+%28MRv1%29+on+a+Cluster#DeployingMapReducev1%28MRv1%29onaCluster-Step7
Has anyone else encountered this? Let me know if you need more information, and thanks for your time.
