>
> In the test environment, when snapshoting the null table (with no data),
> snapshot artifact can be generated successfully with snapshot meta data,
> while there is no CF data under region dir. Then when exporting this null
> snapshot via ExportSnapshot, "java.io.IOException: No input paths specified
> in job" occurred, which affects the normal application flow.
> But seems snapshot for null table also makes sense just with the meta
> information (.snapshot/), although ".archive/" does not show up. Later
> snapshot restore seems work from this "dummy" snapshot artifact with no CF
> data.
> Just eliminate exception for ExportSnapshot against the null table snapshot
> to make application work through.
