Mark Grover commented on BIGTOP-811:
------------------------------------
The intent and idea is great. Thanks, Sean!
A couple things:
1. May I propose that we provide a configuration property that can be used to
override the location (unless we already do so) of mysql-connector-java.
2. Should we call it mysql-connector-java or keep the generic like
sql-connector-java so the same idea can apply to other sql connectors that
aren't shipped with the distribution.
3. Can you think of a scenario where different components would want to use
different versions of connectors (arguably connecting to different databases)?
As a good engineering practice, I'd expect users to use the same relational
database for say sqoop and hive metastores but if they have a separate
metastore for sqoop and separate metastore for hive and their versions
mismatch, they would need separate connectors for these. If you consider this
to be a reasonable use case, we obviously can't help them here so let's make
sure we don't make their life more difficult either.
Thoughts?
> Auto-detect MySQL-Java connector

> Key: BIGTOP-811
> URL: https://issues.apache.org/jira/browse/BIGTOP-811
> Project: Bigtop
> Issue Type: New Feature
> Reporter: Sean Mackrory
> Assignee: Sean Mackrory
>
> For components that require the installation of additional artifacts that
> Bigtop cannot distribute (due to license incompatability or other issues),
> Bigtop should provide both a standardized location to which the artifacts can
> be installed, and the ability to auto-detect the locations to which they may
> already be installed.
> Specifically, Sqoop and Hive (and possibly other components) require the
> installation of the MySQL-Java connector when using MySQL for imports,
> exports, or metadata storage. This needs to be done by copying the JAR to a
> directory that is already in the classpath for those components (such as
> /usr/lib/sqoop/lib and /usr/lib/hive/lib). Some repositories distribute
> packages that install the jar to /usr/share/java.
