Phabricator commented on HIVE-3772:
-----------------------------------
zshao has requested changes to the revision "[jira] [HIVE-3772] Fix a
concurrency bug in LazyBinaryUtils due to a static field (patch by Reynold
Xin)".
Please take this opportunity to fix all static variables in this file.
By the way, a better way to fix is to use ThreadLocal. That's more
effiicient because then we don't need to call new in these low-level functions.

Is this a problem for multi-threaded access as well?
