> Now DataNode only support scan all blocks periodically.  Our site need a tool to check some blocks and files manually. 
> My current design is to add a parameter to DFSck to indicate deeply and manually fsck request, then let NameNode collect property block identifies and sent them to associated DataNode. 
> I'll let DataBlockScanner runs in two ways: periodically ( original one ) and manually. 
> Any suggestions on this are welcome.
