Christopher Tubbs commented on ACCUMULO-4701:
---------------------------------------------

[~vines] Any form of bundling (shading is a form of bundling, with API 
relocation) introduces a whole class of problems (which we can discuss on the 
mailing list if you like). If, as a project, we were to start doing this, I 
think it would require more careful consideration, discussion, and debate (and 
the mailing lists are more suited to that than the JIRA comments section).

ACCUMULO-4702 takes a much more conservative approach, by simply avoiding 
unstable Guava APIs (those marked "Beta"), which we always should have been 
avoiding. This is not a "short-sighted" solution, but a cautious and 
conservative one, which has more limited implications than simply shading Guava.

>  connector embeds Accumulo client {{org.apache.accumulo:accumulo-core}}. 
> Accumulo uses Guava. Since Guava APIs are not strictly backwards compatible, 
> it's necessary to shade guava dependency or library users need to use same 
> Guava version (i.e. cannot upgrade/downgrade at will).
> Please shade Guava dependency.
