Subject [jira] [Created] (HDFS-10758) ReconfigurableBase can log sensitive information
Date Fri, 12 Aug 2016 14:54:20 GMT
Sean Mackrory created HDFS-10758:
------------------------------------

             Summary: ReconfigurableBase can log sensitive information
                 Key: HDFS-10758
                 URL: https://issues.apache.org/jira/browse/HDFS-10758
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Sean Mackrory
            Assignee: Sean Mackrory


ReconfigurableBase will log old and new configuration values, which may cause sensitive parameters
(most notably cloud storage keys, though there may be other instances) to get included in
the logs. 

Given the currently small list of reconfigurable properties, an argument could be made for
simply not logging the property values at all, but this is not the only instance where potentially
sensitive configuration gets written somewhere else in plaintext. I think a generic mechanism
for redacting sensitive information for textual display will be useful to some of the web
UIs too.
