[jira] [Commented] (KUDU-1571) Removal of metrics from CSD MDL breaks CM

["Todd Lipcon (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KUDU-1571?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15429041#comment-15429041 ] 

Todd Lipcon commented on KUDU-1571:
-----------------------------------

I reported this issue to the CM team at Cloudera, but sounds like it will be a while before the NPE will be fixed. In the meantime, and to support upgrade for users of earlier CM versions, we should make our 'generate_mdl.py' script generate stub metrics definitions for the removed metrics that are marked as 'deprecated'.

> In 0.10.0 we removed a couple of metrics (by renaming remote bootstrap to tablet copy). Unfortunately those metrics are relied upon by CM for some of its dashboards, and CM gets an NPE when trying to load those dashboards using the 0.10.0 CSD.
