Rakesh R commented on ZOOKEEPER-2211:
-------------------------------------

Thanks [~arshad.mohammad] for taking this ahead. Patch looks overall fine, just 
few comments:

# Please add one more validation to check the {{-n}} argument name. If user 
pass an argument other than "-n", then should fail. Since its not using command 
line parser, we could add a simple check like  "-n".equals(argOption)
# instead of {{minimum value is 3}}, can you rephrase it to {{greater than 3}}.
{code}
System.out.println("\tcount -- the number of old snaps/logs you want to keep, 
value should be greater than 3");
{code}

> PurgeTxnLog does not correctly purge when snapshots and logs are at different 
> locations

> PurgeTxnLog does not work when snapshots and transaction logs are at 
> different file paths. The argument handling is buggy and only works when both 
> snap and datalog dirs are given, and datalog dir contains both logs and snaps 
> (snap is ignored).
