Yan commented on RANGER-1521:
-----------------------------
A few comments:
1) There are a few workarounds to address the data corruption issue. The one
mentioned above comes from
https://community.hortonworks.com/questions/23647/ranger-admin-install-fails-with-007-updateblankpol.html
2) Use of Now() probably won't serve the purpose of uniqueness for "transaction
ID" given its second-level granularity;
3) More knowledge about the use of "transaction id" in Ranger is desired. If it
is of no practical use, it should be considered to be removed at all; if it is
used for identification purpose, the uniqueness requirement would be important.
May the community shed more lights on this?
4) Ranger intrinsic logic to create transaction ID utilizes some random #
generation. Not sure whether it would be compatible with the timestamp-based
IDs as proposed here.

> non-deterministic functions and are causing failures on replicated MySQL
> database.
