Hi,    Executing "hdfs dfs -ls /", we are getting a KrbException: Fail to create credential. (63) - No service creds even with a valid kerberos ticket on a particular Kerberos realm.   We've been looking into the source code of the JVM and we think we might find the cause with DEBUG level. According to http://hadoop.apache.org/docs/r2.7.1/hadoop-project-dist/hadoop-hdfs/HDFSCommands.html, there is a loglevel option to the hdfs command. So we launch it like this:   hdfs dfs -ls / --loglevel DEBUG   But that seems to have no effect (only WARN is getting printed). How can we control the loglevel?   Thanks in advance ... View more

Hello,   From a non-superuser accout, I created a workflow and I shared it with the group "visualization" in read only mode:     The super-user "admin" is member of the "visualization" group and "default" group only. As can be seen from above screenshot, the workflow is not shared with no other user/group.   But, I discovered that the user "admin" is able to edit and save the workflow without restrictions:   How is it possible that a user is able to edit a workflow when he should not be able to do so? Thanks in advance   ... View more

Hello,   I ask here for an advice on hue configuration. We are developing a KDC security-enabled cluster with multiple users belonging to various groups. Currently we rely heavily on Hue and Oozie workflows that are designed from Hue. Users create their workflows under their user in Hue. Workflows of a particular user are not accessible to others from the list of workflows, unless explicitly shared, which is fine.    However there are problems we'd like to solve:   1. Other users still can access workspaces of those workflows via HDFS, either with Hue's "File browser" or directly via hdfs command. Particulary from Hue, seems that anyone can access workspace directory and even open its files, even if I explicitly change the dir and files permission to 600. (See screenshot attached)   2. The properties of the launched workflows can be seen by other users in the "Configuration" tab, regardless of their permissions on the workflow. Can those values be hidden somehow?   Thanks in advance!   ... View more
