Hi all,
currently, we try to upgrade from hadoop-0.19 to hadoop-0.20. Therefore,
we try to get rid of the deprecated JobConf class and switch to
org.apache.hadoop.mapreduce.Job where possible.
In several projects we have chained jobs which depend on each other. For
these, we used the Job and JobControl classes of the
org.apache.hadoop.mapred.jobcontrol package which rely on the deprecated
JobConf class.
How does chaining of dependent jobs work with hadoop-0.20+? Do we still
have to use the org.apache.hadoop.mapred.jobcontrol package or is there
a better way using only the org.apache.hadoop.mapreduce.Job class?
Is there a plan to move org.apache.hadoop.mapred.jobcontrol to a package
org.apache.hadoop.mapreduce.jobcontrol in the future?
Regards,
Thomas
