Mark Grover commented on BIGTOP-811:
------------------------------------
Sean,
This looks good to me overall.
A few minor suggestions:
1. The patch doesn't apply cleanly anymore. Can you please update it?
2. I would still personally like to see a template entry for how to override
BIGTOP_CLASSPATH in bigtop-utils.default
(https://github.com/apache/bigtop/blob/master/bigtop-packages/src/common/bigtop-utils/bigtop-utils.default)
May be something like:
{code}
# Override Bigtop classpath for including common jars (e.g. database
connectors, etc.) in classpath of various components of Bigtop distribution.
Only needed for including jars outside of /var/lib/bigtop.
# export BIGTOP_CLASSPATH
{code}
What do you think?
It's also worth pointing out somewhere in code/comment/documentation that
{{BIGTOP_CLASSPATH}} currently only is used by Hive. Sqoop, Oozie bypass and
directly add things to tomcat's classpath without observing what's in
BIGTOP_CLASSPATH.
> Add /var/lib/bigtop as a location to install SQL connectors and other plug-ins

> 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.
