However, in > hadoop 23, org.apache.hadoop.mapred.Counters does not implement getGroup(). > Its > parent class AbstractCounters implements it. This is different from hadoop20X. > As a result, Oozie compiled with either hadoop version does not work with the > other version. > A specific scenario, Oozie compiled with .23 and run against 205, does not > update job status owing to a Counters API exception. > Will explicit re-compilation against the relevant hadoop jars be required each > time? This will prevent launching a uniform Oozie version across different > clusters. -- This message is automatically generated by JIRA.
