It will make huge lose if Hbase loses any cell of data. Any ways that I can check the data consistent with the source data? What if my data lose, how do I know how many records I should restore it from my backup source? Also, the security is an important part; how can I tell my boss we can put it onto production without any security control. Any suggestions?
