Arpit Agarwal updated HADOOP-12746:
-----------------------------------
Description:
{{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values queried via {{getConf().get(...)}} can be outdated.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.
was:
{{ReconfigurableBase}} does not always update the cached configuration after a
property is reconfigured.
The older {{#reconfigureProperty}} does so however {{ReconfigurationThread}}
does not.
