Subject [jira] [Commented] (SENTRY-430) Sentry Service does not use correct classpath when HIVE_HOME environment var is defined
Date Thu, 18 Sep 2014 05:22:35 GMT

    [ https://issues.apache.org/jira/browse/SENTRY-430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14138527#comment-14138527

Lenni Kuff commented on SENTRY-430:
-----------------------------------

bq. Hence the script makes the assumption that when you have Hive env set, then you are invoking
config tool and doesn't include server jars in the classpath.

This seems a bit unintuitive to me. I think it is strange that just having HIVE_HOME set causes
this sort of behavior change when starting up the service. It's also strange that the CLASSPATH
will get filled with a bunch of Hive JARs, which (as we see from this bug) cause Sentry Service
to fail to work properly.

> When HIVE_HOME is set as an environment variable, the Sentry Service will not run with
the correct classpath when invoked using "bin/sentry". 
> The code below is from "bin/sentry". Note how if HIVE_HOME is defined nothing from lib/server/*
is added to the classpath.
> As a side note, it seems strange that there even is a reference to Hive in this context.
It seems that the sentry service is being executed via Hive when HIVE_HOME is defined. It
seems like we should not do this.
