Local mode seems to be broken in Cloudera's 737 release
-------------------------------------------------------
Key: MAPREDUCE-2194
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2194
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 0.20.2
Reporter: Alex Rovner
We have upgraded our dev environment from Cloudera's 0.20.2-228-cloudera to
0.20.2-737-cloudera
Version 228 worked great for us. In version 737 we are getting the following
exception:
(LocalJobRunner.java:295) - job_local_0005
java.lang.ClassCastException: org.apache.hadoop.mapreduce.lib.input.FileSplit
cannot be cast to org.apache.hadoop.mapred.InputSplit
at org.apache.hadoop.mapred.MapTask.runOldMapper(MapTask.java:357)
at org.apache.hadoop.mapred.MapTask.run(MapTask.java:317)
at
org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:212)
We have tried to set
job.getConfiguration().setBoolean("mapred.reducer.new-api", true) but that did
not resolve the issue.
