Subject [jira] [Commented] (AMBARI-2070) Changing service directories should popup a confirmation/warning dialog upon save
Date Thu, 02 May 2013 07:20:15 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-2070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13647361#comment-13647361
] 

Yusaku Sako commented on AMBARI-2070:
-------------------------------------

On HDFS config, if at least one of NameNode directories, SecondaryNameNode Checkpoint directory,
or DataNode directories is edited, a warning confirmation popup appears: "You are about to
make changes to service directories that are core to HDFS. Before you proceed, be absolutely
certain of the implications and that you have taken necessary manual steps, if any, for the
changes. Are you sure you want to proceed?"
On MapReduce config, if either of MapReduce local directories or MapReduce system directories
is edited, a warning confirmation popup appears: "You are about to make changes to service
directories that are core to MapReduce. Before you proceed, be absolutely certain of the implications
and that you have taken necessary manual steps, if any, for the changes. Are you sure you
want to proceed?"
Upon "No", changes are not saved.
Upon "Yes", changes are saved and a popup appears to show the result of the operation (success
or fail).
The warning confirmation popup should NOT appear if none of the directories mentioned is being
changed.

> Post-install, if the user tries to reconfigure NN, SNN, MapReduce local/system directories,
we should popup a confirmation/warning upon Save as this is potentially a dangerous operation.
