> the streaming Jobclient implementation i.e contrib/streaming/src/java/org/apache/hadoop/streaming/StreamJob.java
is significantly different than the core hadoop mapred/org/apache/hadoop/mapred/JobClient.java.
> for example unlike StreamJob.java, JobClient.java it gets tasks log when jobclient.output.filter=ALL
is specified .
> With hod-logs going away in hadoop 0.20 (due to new scheduler) user has no good way of
programmitically getting logs
> We should have intermediate adaptor class to implement Tools for the purpose of submitting
jobs via m/r, streaming, pipes so that we don't miss some core functionality.
>  
> GenericJobClient implements Tools and then StreamJob extends GenericJobClient, JobClient
extends GenericJobClient
