John Yost updated GIRAPH-822:
-----------------------------
Description:
Hi Everyone,
I've run into this really weird error with the following stacktrace:
Exception in thread "main" java.lang.ClassCastException:
org.apache.giraph.conf.GiraphConfiguration cannot be cast to
org.apache.hadoop.mapred.JobConf
at org.apache.hadoop.mapreduce.Job$1.run(Job.java:513)
at java.security.AccessController.doPrivileged(Native Method)
at javax.security.auth.Subject.doAs(Subject.java:415)
at
org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1149)
at org.apache.hadoop.mapreduce.Job.connect(Job.java:511)
at org.apache.hadoop.mapreduce.Job.submit(Job.java:499)
at org.apache.hadoop.mapreduce.Job.waitForCompletion(Job.java:530)
at
com.prototype.analytics.TwitterSpringRunner.run(TwitterSpringRunner.java:58)
at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65)
at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:79)
at
com.prototype.analytics.TwitterSpringRunner.main(TwitterSpringRunner.java:78)
Everything was working fine with my locally-built giraph version, but when I
added the Giraph 1.0.0 maven dependency, this Exception was thrown. Any ideas?
UPDATE:
When I revert back to using GiraphRunner, the job completes successfully, so I
must have dorked up something along the way within my Tool class. Still would
like to know if anyone else has encountered this and how to fix it, thanks.
