Vrushali C commented on YARN-6905:
----------------------------------
So the ApplicationId.toString is being invoked in AppIdKeyConverter#decode
function which is in the hadoop-yarn-server-timelineservice-hbase module. This
module depends on hadoop-yarn-api as well as hadoop-common. So I think moving
the FastNumberFormat from hadoop-common to hadoop-yarn-api may not help.
I think timeline service would need to override the ApplicationId.toString
internally. Or, although I think this won't be very likable, hadoop-yarn-api
can provide a ApplicationId#toStringSlowImpl function (or some such named
function) in ApplicationId itself which keeps the old code instead of the
changes to ApplicationId #toString() in YARN-6768.
Unfortunately, we could see more classpath conflicts as trunk keeps evolving,
till timeline service on trunk can be based on the hbase version which is based
on hadoop trunk.
