Masatake Iwasaki resolved HADOOP-16335.
---------------------------------------
Resolution: Invalid
I think this is coufiguration issue. If you define env var
HDFS_NAMENODE_USER=root in hadoop-env.sh or somewhere and run the command by
another user, you will get the error.
{noformat}
$ HDFS_NAMENODE_USER=root bin/hadoop namenode -format
WARNING: Use of this script to execute namenode is deprecated.
WARNING: Attempting to execute replacement "hdfs namenode" instead.
ERROR: namenode can only be executed by root.
{noformat}
I'm closing this as invalid. Please reopen if this turns out to be bug in
scripts.
