Andrew Wang commented on HDFS-5683:
-----------------------------------
Sorry for letting this sit so long Abhiraj, this patch looks good to me. Audit
logging is very file-centric right now so the semantics don't fit quite right
with the caching methods, but this looks like a strict improvement over what we
have right now.
+1 will commit shortly.
