Sean Busbey commented on HDFS-10758:
------------------------------------
bq. I think a generic mechanism for redacting sensitive information for
textual display will be useful to some of the web UIs too.
Should this be in the Hadoop Common tracker so that the solution can be
leveraged by both HDFS and YARN?

> 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.
