Subject: Add a TAP test to do sanity tests post addition of coordinators/datanodes.
X-Git-Tag: XL_10_R1~27
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=df02f25aba22beddace200639b4adc3e73727c0b;p=postgres-xl.git

Add a TAP test to do sanity tests post addition of coordinators/datanodes.

Its a very simplistic test right now, but hopefully we can extend this further
in the coming time.
