[ https://issues.apache.org/jira/browse/PIG-3499?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13785702#comment-13785702 ]
Prashant Kommireddi commented on PIG-3499:
------------------------------------------
[~kdvenkata] - why is local mode using HA? Are you sure you are running Pig's local mode?

> Key: PIG-3499
> URL: https://issues.apache.org/jira/browse/PIG-3499
> Project: Pig
> Issue Type: Bug
> Components: grunt, parser, tools
> Affects Versions: 0.10.0
> Reporter: venkata kamalnath
>
> when we run a pig script with namenode HA(QJM) we always get unknown host exception. The nameserviceID is being considered as host and pig job giving unknown host exception.
> I am working on this fix but want community to validate whether any bug reported similar to this. If not I will provide the fix as soon as possible.
> The pig script is as below:
> testTable = LOAD 'hdfs://kdvenkata/user/kd/test.csv'
> USING PigStorage(',')
> AS (col1:chararray, col2:chararray, col3:int);
> STORE testTable into '/tmp/test_pig_output';
> Exception:
> Caused by: java.lang.IllegalArgumentException: java.net.UnknownHostException: kdvenkata
