Rajkumar Singh commented on HIVE-19661:
---------------------------------------
Hi [~sershe] thanks for looking into this
1) Is context needed in the UDF object other than to get the config? to access
the property at job runtime we need to access it from job context.
2) Re2J license needs to be added to the file with other licenses to LICENSE
file. Added to LICENSE
3) Also build appears to have failed. Looks like HiveConf changes are missing
from the patch file. Added complete patch for review.
> switch Hive UDFs to use Re2J regex engine
