Does Drill support High Available (HA) Hadoop?

Hello,

I am evaluating Drill 1.2 but I have not managed to make it work.
Does anyone know if Drill supports Hadoop in High Available (HA) mode?

Error:
---
2015-11-14 00:47:44,674 [Client-1] ERROR
o.a.d.exec.server.rest.QueryWrapper - Query Failed
org.apache.drill.common.exceptions.UserRemoteException: SYSTEM ERROR:
UnknownHostException: HDP

I have seen a post with a similar issue:

Regards and thanks in advance for any help.

Which settings are specifically needed to add to the hdfs-site-xml to make
this work? Do we have a JIRA tracking this?

thanks

Sebastian,

I was able to work around that bug by copying the hdfs-site-xml file into Drill's conf folder. Then restart the drillbit. 

The reason this works is inside the hdfs-site.xml file are definitions of the HDFS HA cluster. Hopefully Drill fixes this bug soon.
