Eric Hanson commented on HIVE-4624:
-----------------------------------
This patch includes both changes to VectorizationContext to enable SUBSTR() to
run end-to-end, but also bug fixes and unit test fixes related to
StringSubstrColStart and StringSubstrColStartLen. I did ad hoc tests from the
console to test a large number of variations of use of SUBSTR() in vectorized
mode.
