    Additional info-

    When attempting to restart HUe the following now happens:

    "Command failed to run because service hue has invalid configuration. Review and correct its configuration. First error: Missing required value: HDFS Web Interface Role"

    Can you please send us logs for CM server
    (/var/log/cloudera-scm-server/cloudera-scm-server.log)?

    Are you able to access Hue service's Configuration page? If so you can set
    the HDFS Web Interface Role and then you should be able to start Hue.

    You can try setting the "hue_webhdfs" property using CM's REST API and see
    if that makes a difference.

    BTW how did you reach into this situation? Were you relocating NameNode or
    HTTPFS role in HDFS?

    I was setting up HA on the cluster so that I could have flume write to
    either namenode. That seemed easy enough - a few clicks and done.

      What I didn't expect is seeing a config warning message for Hue. The warn
    message related to selecting HTTPFS or WebHDFS on one of the nodes. This
    was displayed in the config tab in the Hue service and there was 2 choices
    - namenode1 and 2. Node 1 being selected. I selected the 2nd namenode and
    clicked saved. Restarted Hue and had the same warning. I repeated the
    process and selected namenode 1 and saved the change. This time however it
    didn't seem to take and I selected save again and got the error message
    that I posted - almost as if the config was in mid save when it was it was
    resaved again, thus clobbering the config.

    Is there a specific config file in the cluster that controls Hue or the
    config saved in the embedded db? I've looked at the hue,ini and don't see
    anything that related.

    The warning means that if you have HA HDFS, then you should add an HTTPFS
    role to HDFS and then set that role has HDFS Web Interface Role for Hue.
    This config is saved in CM database. I wouldn't recommend modifying the db
    directly. You should set "hue_webhdfs" property using the API. The value
    can be the name of any of the NameNodes. (You can get the name of Namenode
    using API as well).

    Once the config is set, the error should go away. You can then add the
    HTTPFS role and set Hue's webinterface to that role.

    Hi Tim -

    You can use a curl command of the form:

    curl -X PUT -H "Content-Type:application/json" -u <CM_USER>:<CM_PASS> \
       -d '{ "items": [
             { "name": "hue_webhdfs", "value": "<NAMENODE_NAME>" } ] }' \
       'http://
    <CM_SERVER_HOST>:7180/api/v6/clusters/<CLUSTER_NAME>/services/<HUE_SERVICE_NAME>/config'

    Where:

       <CM_USER> is the admin user name you use to login to
    the CM UI
       <CM_PASS> is the password for the admin user
       <NAMENODE_NAME> is the role name of the Namenode you want to set
    hue_webhdfs to
       <CM_SERVER_HOST> is the hostname of the host where CM Server is running
       <CLUSTER_NAME> is the name of the cluster
       <HUE_SERVICE_NAME> is the name of the Hue service

    You can use the API to find the values for <NAMENODE_NAME>, <CLUSTER_NAME>
    and <HUE_SERVICE_NAME>. One way to do this is:

    1. From the CM UI, click "Support" near the upper right corner.
    2. Select "API Documentation" from the drop-down menu.
    3. This will take you to the API documentation page. Scroll down and click
    on "/clusters" under "REST Resources."
    4. This takes you to a page documenting the "/clusters" endpoint. Clicking
    on the link next to "Mount Point" will execute a GET of this resource on
    your CM server, which will display a JSON document listing the clusters
    managed by CM. The cluster names are included in this list.
    5. Now that you've got the cluster name, use it to access the
    /clusters/{clusterName}/services API resource. Remember to URL encode the
    cluster name (e.g., encode space characters as %20). This will generate a
    JSON showing the Hue service name.
    6. Continue in this way to obtain the Namenode role name
    (/cluster/{clusterName}/services/{serviceName}/roles).

    You will end up with a curl command that looks something like:

    curl -X PUT -H "Content-Type:application/json" -u
    admin_user:admin_user_passwd \
       -d '{ "items": [
             { "name": "hue_webhdfs", "value":
    "HDFS-1-NAMENODE-8d3f52189a7ba760ade71a078c93f41c" } ] }' \
       'http://cm.foo.com:7180/api/v6/clusters/Cluster%201/services/HUE-1/config'

    For more information, there is a link to an API tutorial on the API
    Documentation page.

    Subject: Re: Lost Hue config while resetting HTTPFS/WebHDFS - How
    fix???
    ------------------------------




    You can try setting the "hue_webhdfs" property using CM's REST API and see
    if that makes a difference.

    BTW how did you reach into this situation? Were you relocating NameNode or
    HTTPFS role in HDFS?
