> I enabled the permission management in my hadoop cluster, but I'm facing a
> problem sending jobs with pig. This is the scenario:
> 1 - I have hadoop/hadoop user
> 2 - I have myuserapp/myuserapp user that runs PIG script.
> 3 - We setup the path /myapp to be owned by myuserapp
> 4 - We set pig.temp.dir to /myapp/pig/tmp
> But when we pig try to run the jobs we got the following error:
> job_201303221059_0009 all_actions,filtered,raw_data DISTINCT
> Message: Job failed! Error - Job initialization failed:
> org.apache.hadoop.security.AccessControlException:
> org.apache.hadoop.security.AccessControlException: Permission denied:
> user=realtime, access=EXECUTE, inode="system":hadoop:supergroup:rwx------
> Hadoop jobtracker requires this permission to statup it's server.
> My hadoop policy looks like:
> <property>
> <name>security.client.datanode.protocol.acl</name>
> <value>hadoop,myuserapp supergroup,myuserapp</value>
> </property>
> <property>
> <name>security.inter.tracker.protocol.acl</name>
> <value>hadoop,myuserapp supergroup,myuserapp</value>
> </property>
> <property>
> <name>security.job.submission.protocol.acl</name>
> <value>hadoop,myuserapp supergroup,myuserapp</value>
> <property>
> My hdfs-site.xml:
> <property>
> <name>dfs.permissions</name>
> <value>true</value>
> </property>
> <property>
> <name>dfs.datanode.data.dir.perm</name>
> <value>755</value>
> </property>
> <property>
> <name>dfs.web.ugi</name>
> <value>hadoop,supergroup</value>
> </property>
> My core site:
> ...
> <property>
> <name>hadoop.security.authorization</name>
> <value>true</value>
> </property>
> ...
> And finally my mapred-site.xml
> ...
> <property>
> <name>mapred.local.dir</name>
> <value>/tmp/mapred</value>
> </property>
> <property>
> <name>mapreduce.jobtracker.jobhistory.location</name>
> <value>/opt/logs/hadoop/history</value>
> </property>
> <property>
> <name>mapred.jobtracker.taskScheduler</name>
> <value>org.apache.hadoop.mapred.FairScheduler</value>
> </property>
> Ps: This works with Capacity Scheduler
