Hi Scott,
Bingo. Just tried this very case with the sample file from the previous post.
Got exactly the failure in the post you provided. I notice that a "select *"
query returns immediately, but a "count(*)" query hangs for the 30+ seconds
before it errors out. Mine is only a two-record file,
Paul,
Thanks for prompting the right questions. I went back and took another look
at my queries. It turns out that there is some condition that causes this
error when running functions like "count(*)" on the data to cause this
error, where a normal unqualified select does not. I also ran across
A simple linux GREP command can be used to find data, but trying to GREP a JSON
file with no line breaks just returns back a wall of text..

fixed in? The ticket I referenced is still open, with no comments.

Hi David,
JSON files are never splittable: there is no single-character way to find the
start of a JSON record within a file.
Drill is supposed to support two JSON formats: the array format from the
earlier post, and the non-JSON (but very common) list of objects format in this
example.
