Date: Tue, 17 Aug 2010 11:39:47 -0400 X-Mailer: Apple Mail (2.936) X-Virus-Checked: Checked by ClamAV on apache.org Hi All, We have strange issue here. We have 10 nodes cross 5 datacenters. Today I found a strange thing. On one node, few data deleted came back after 8-9 days. The data saved on a node and retrieved/deleted on another node in a remote datacenter. The CF is a super column. What is possible causing this? Thanks, Zhong Li
