Review request for ranger, Madhan Neethiraj, Ramesh Mani, and Velmurugan
Periasamy.
Bugs: RANGER-3192
https://issues.apache.org/jira/browse/RANGER-3192
Repository: ranger
Description
-------
Use concurrent read-write lock to ensure that access evaluation and policy/tag
updates are mutually exclusive in multi-threaded environment
Ranger uses copy and switch method to handle reads and writes to policy and tag
repositories in a multi-threaded environment. Using read/write lock to handle
concurrent accesses will save on copy which is more memory and CPU efficient.
