Subject [jira] [Commented] (HIVE-15448) ChangeManager for replication

Thejas M Nair commented on HIVE-15448:
--------------------------------------

[~sushanth] Where would this "Path getCMPath(Path path, Configuration conf)" call be made
from ? During 'repl load' , only 
getCMPath(Path path, Configuration conf, String signature) should be used.
