Subject [jira] [Created] (HBASE-7851) Include the guava classes as a dependency for jobs using mapreduce.TableMapReduceUtil
Date Thu, 14 Feb 2013 23:33:13 GMT
Devaraj Das created HBASE-7851:

             Summary: Include the guava classes as a dependency for jobs using mapreduce.TableMapReduceUtil
                 Key: HBASE-7851
                 URL: https://issues.apache.org/jira/browse/HBASE-7851
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.94.4
            Reporter: Devaraj Das
            Assignee: Devaraj Das
             Fix For: 0.94.6

The guava classes go as a dependency for jobs using TableMapReduceUtil from the  org.apache.hadoop.hbase.mapred
package but the same doesn't happen for jobs using the same class from org.apache.hadoop.hbase.mapreduce
package. Due to this, tasks of the mapreduce jobs that wants to communicate with a secure
cluster fails. The stack trace of the failing tasks:
Error: java.lang.ClassNotFoundException: com.google.common.collect.ImmutableSet
	at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
	at java.security.AccessController.doPrivileged(Native Method)
	at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
	at org.apache.hadoop.hbase.ipc.SecureServer.<clinit>(SecureServer.java:96)

We just need to add the dependency on the guava classes in the mapreduce.TableMapReduceUtil
