Hue problem
ivaylo frankov 2013-11-17, 21:11
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.

When I start pig shell I receive :
Error: value 0 for UID is less than the minimum UID allowed (500)

T
Thank you for your help once again!

Cheers,
Ivo
