Michael Gokhman commented on DRILL-3478:
----------------------------------------
in Drill 1.4, SELECT-ing an {{_id}} results in:
{code}
{"$oid":"567ff2697f2310849fea0666"}
{code}
as expected.
however, when working with the master branch, SELECT-ing an {{_id}} results in
a blob, something like:
{code}
[B@3149a…]
{code}
I'm pretty sure this patch, or DRILL-4242 is the source of the problem
thank you
