Dick King updated MAPREDUCE-1505: --------------------------------- Status: Patch Available (was: Open) > Cluster class should create the rpc client only when needed > ----------------------------------------------------------- > > Key: MAPREDUCE-1505 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1505 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: client > Affects Versions: 0.20.2 > Reporter: Devaraj Das > Assignee: Dick King > Fix For: 0.22.0 > > Attachments: mapreduce-1505--2010-05-19.patch, > MAPREDUCE-1505_yhadoop20.patch, MAPREDUCE-1505_yhadoop20_9.patch > > > It will be good to have the org.apache.hadoop.mapreduce.Cluster create the > rpc client object only when needed (when a call to the jobtracker is actually > required). org.apache.hadoop.mapreduce.Job constructs the Cluster object > internally and in many cases the application that created the Job object > really wants to look at the configuration only. It'd help to not have these > connections to the jobtracker especially when Job is used in the tasks (for > e.g., Pig calls mapreduce.FileInputFormat.setInputPath in the tasks and that > requires a Job object to be passed). > In Hadoop 20, the Job object internally creates the JobClient object, and the > same argument applies there too. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
