Varun Saxena commented on HADOOP-12098:
---------------------------------------
Tests fail due to runtime dependence on jobclient main jar. The test jar and hs
jars are still unnecessary.
The runtime dependence comes due to subclasses of {{ClientProtocolProvider}}
classes being loaded at runtime
{{ClientProtocolProvider}} exists in {{hadoop-mapreduce-core}}.
{{LocalClientProtocolProvider}} and associated classes such as
{{LocalJobRunner}} exist in {{hadoop-mapreduce-client-common}}
{{YarnClientProtocolProvider}} and associated classes such as {{YarnRunner}}
exist in {{hadoop-mapreduce-jobclient}}.
Any reason why these classes have been kept this way ? All can move to
{{hadoop-mapreduce-client-core}} IMHO. This creates unnecessary dependencies.
{{hadoop-mapreduce-client-jobclient}} seems to be having hardly any main
classes now. Is it even required as a separate submodule ?
