Subject: [PATCH] Issue 37:	Replicate delete

Reported by hieu.hcmus, Today (24 minutes ago)


What steps will reproduce the problem?
1.Create 2 volumes server same rack, replication type = 001
2.Upload a file
3.Delete file

What is the expected output? What do you see instead?
Expected output: File is deleted in both volume server
But: file is only deleted in one volume server

What version of the product are you using? On what operating system?
0.36
Please provide any additional information below.

After remove NeedleValue from NeedleMap, the size = 0 and it causes the
error.
