Hi, I am trying to run chained jobs using Hadoop 0.20.2. I see that the class JobControl is provided for the same purpose in 0.20.2. However, I can only add the deprecated class org.apache.hadoop.mapred.jobcontrol.Job. For using the JobControl class I need to use the older deprecated Job class and the other deprecated classes from the mapred package e.g. JobConf, etc. to be able to use JobControl. I am starting out developing infrastructure for us to create jobs etc and dont want to use deprecated classes/packages preferably.
In Hadoop 0.21.0, I have seen there is another class ControlledJob and JobControl in the mapreduce.lib.jobcontrol package that takes care of this. However 0.21.0 is not production ready as mentioned on the Hadoop site. What is the suggested course of action in this case? I see that using deprecated classes is the only option I see. Actualy, using deprecated classes will cause quite a few cascading changes, so I am trying to not do that if possible. Thanks Sarthak Dudhara
