Description

git.commit.id.abbrev=38ef562

The below query did not fail when I ran it in isolation. However when I ran the test suite at [1], which also contains the below query, by using 50 threads submitting queries concurrently, I hit the below error.

select boolcol, bigintegercol, varcharcol, kvgen(bigintegercol), kvgen(boolcol), kvgen(varcharcol) from `json_kvgenflatten/kvgen1.json`
Failed with exception
java.sql.SQLException: SYSTEM ERROR: DrillRuntimeException: kvgen function only supports Simple maps as input
