Hi Brian, I am not seeing this trouble on a similar version locally:
harsh@~]$ hadoop fs -ls drwxr-xr-x - harsh harsh 0 2012-09-28 04:21 outfoo [harsh@~]$ hadoop fs -chmod 1777 outfoo [harsh@~]$ hadoop fs -chmod -R 1777 outfoo [harsh@~]$ hadoop fs -chmod -R +t outfoo [harsh@~]$ What is your JVM/Java version? There's one known issue with Java 7 (vs. 6) that may break things in the regex areas (I recall Oozie facing a similar issue with one of the Patterns it was using). Make sure you use Java 6 (1.6) for now, until there's been more testing with Java 7 for Hadoop/etc. On Wed, Nov 7, 2012 at 11:27 PM, Brian Derickson <bderickso...@gmail.com> wrote: > Hey all, > > 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?
