Subject Re: Unable to detect files in hadoop file system from apache drill 0.9.0
Date Thu, 07 May 2015 14:34:41 GMT
Hi Sharath,

Sorry for the trouble. Could you try after adding the following to your
core-site.xml of HDFS on all nodes and restart?

Replace <DrillbitUser> with userName of the user who is running the
Drillbit process.

<property>
   <name>hadoop.proxyuser.<DrillbitUser>.hosts</name>
   <value>*</value>
</property>
   <property>
<name>hadoop.proxyuser.<DrillbitUser>.groups</name>
  <value>*</value>
</property>

This seems to be a regression from one of the impersonation changes we
added in 0.9.0

Thanks
Venki
