[jira] [Commented] (PIG-2162) bin/pig should not modify user args

["Raghu Angadi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-2162?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13064919#comment-13064919 ] 

Raghu Angadi commented on PIG-2162:
-----------------------------------

There is a related issue with parsing of params inside PIG. We need to escape '=' and any space before '=' which specifying params on command line, but there is is no such restriction for using '%default'. We might need merge the parser for these two. This might a relatively minor tweak to ParamLoader.jj. 

to get equivalent of {{%declare cond 'i == 2'}} we need to use {{ -p cond='i\ \=\= 2' }}

> PIG launcher script (bin/pig) joins all the user arguments in one string. This leads to confusion when the arguments contain spaces.
> i.e. '{{bin/pig -p sub="i > 2"}}' is should not same as '{{bin/pig -p "sub" "i" ">" "2"}}', but it is.
