[jira] [Commented] (PIG-2920) e2e tests override PERL5LIB environment variable

["Rohini Palaniswamy (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-2920?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13462467#comment-13462467 ] 

Rohini Palaniswamy commented on PIG-2920:
-----------------------------------------

Removing it altogether might cause tests to fail as test/e2e/pig/testdist/libexec has some perl modules.

Can you instead set a property with default value as ./libexec and use the property name in the env element. It would be similar to other overridable properties with default value like harness.PH_LOCAL.

> I am not sure why but e2e tests set PERL5LIB like this:
> {code}
> <env key="PERL5LIB" value="./libexec"/>
> {code}
> This overrides any env variable, so there is no way to use custom Perl installations.
> This patch just removes the line, thus we will rely on the user to configure PERL5LIB appropriately.
> With this modification I am able to use my custom Perl installation.
