Yiqun Lin commented on HDFS-12772:
----------------------------------
Hi [~elgoiri], just some initial comments for the patch:
*RouterStore .java*
1. The method name {{getRouterRegistration}} and {{getRouterRegistrations}} is
so similar, can we rename {{getRouterRegistrations}} to other name?
*GetRouterRegistrationResponse .java*
Why not also add the field of timestamp in this class like
\{{GetRouterRegistrationsResponse }} has?
*GetRouterRegistrationRequest .java*
Can we update the parameter name {{public abstract void setRouterId(String
router);}} from {{router}} to {{routerId}}?
*RouterHeartbeatRequest .java*
Can we using the paramter {{routerState}} or {{state}} instead of {{router}}?
*RouterHeartbeatRequestPBImpl .java*
Please format line {{RouterStatePBImpl routerPB = (RouterStatePBImpl)router;}}.
*RouterState.java*
Why we use compile date info for setting {{buildVersion}}? Maybe we should add
a new method (like {{org.apache.hadoop.util.VersionInfo._getBuildVersion()}})
in class FederationUtil and use that?
*StateStoreVersion.java*
I'm not so clear for the usage of this class. Would you document the javadoc
for this class?
BTW, please fix the compile error in the next patch. Would you mind filling
other JIRAs for tracking the remaining work?
