> {{ReconfigurableBase#startReconfigurationTask}} does not update its cached
> configuration after a property is reconfigured. This means that configuration
> values queried via {{getConf().get(...)}} can be outdated. One way to fix it
> is {{ReconfigurableBase#reconfigurePropertyImpl}} returns the new effective
> value of the config setting and caller i.e. ReconfigurableBase will use it to
> update the configuration.
> See discussion on HDFS-7035 for more background.
