Regarding SLF4J and what should or shouldn't be included in the JDBC-all
Jar file:
Do we intend that someone using the JDBC-all Jar file can turn on Drill
JDBC-layer logging by adding to the class path only a logback.xml file (that
is, without adding additional Jar files/classes)? If so, then it seems like
the JDBC-all Jar file is probably missing the logback-classic Jar file (which
contains a org.slf4j.impl.StaticLoggerBinder).
Or is it the case that we're leaving out back-end SLF4J libraries/classes
on purpose (perhaps to avoid interfering with the user's choice of which back
end to use)?
