Hallo Roman,
I try to config oozie . Unfortunately I can not start web console
althowgh I made every thing after user manual.
I found that I have to configure this core-site.xml in the following way
<!-- OOZIE -->
<property>
<name>hadoop.proxyuser.[OOZIE_SERVER_USER].hosts</name>
<value>[OOZIE_SERVER_HOSTNAME]</value>
</property>
<property>
<name>hadoop.proxyuser.[OOZIE_SERVER_USER].groups</name>
<value>[USER_GROUPS_THAT_ALLOW_IMPERSONATION]</value>
</property>
I attach my core-site.xml . My user is oozie as in psecification of cloudera.
I use the file in /etc/hadoop/conf.pseudo
I make something false and I would be very thankfull to you to tell me what ;)
I extracted also extJS in /var/lib/oozie.
Thank you very much once again!
Best regards,
Ivo

Dear Bruno,
Thank you very much. Thanks you help I succeed to start HBase I even see it
in HUE.
Unfortunatelly I have other problem with HUE. In fact 2 problems.
When I try to see what is on HDFS I receive :
Cannot access: /. Note: You are a Hue admin but not a HDFS superuser (which
is "hdfs").
I tried to change hdfs-site.xml
<configuration>
<property>
<name>dfs.permissions</name>
<value>false</value>
</property>
<property>
<name>dfs.web.ugi</name>
<value>root,root</value>
</property>
</configuration>
But without success.
The second is I can not start pig shell (and pig IDE) in HUE.
For Hue access to HDFS I'd actually recommend configuring
Hadoop's HTTPFS. I find it a little bit more convenient that
way:
http://hadoop.apache.org/docs/r2.2.0/hadoop-hdfs-httpfs/index.html
When I start pig shell I receive :
Error: value 0 for UID is less than the minimum UID allowed (500)
It looks that somehow you're ending up logging in Hue as root (UID 0).
This won't work. You need to create a regular Unix user AND a corresponding
Hue user (just the same user name) to be able to submit jobs.
Thanks,
Roman.
