Gaurav Kanade commented on HADOOP-12717:
----------------------------------------
Can you specify how exactly you are trying to use the ExportSnapshot - i.e. what is the copy-to parameter in your ExportSnapshot? Just want to get a better idea to correctly identify the interactions with our WASB code path
