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?
