Subject What happens when a block is being invalidated/deleted on the DataNode when it is being read?
Date Fri, 01 Feb 2013 03:15:10 GMT
Hi, all

I am wondering if this situation could happen: a block is being
invalidated/deleted on a DataNode(by the NameNode, for example, to delete a
over-replicated block) while it is also concurrently being read (by some
clients). If this could happen, how does hdfs handle this issue?

Thank you very much.

Xiao Yu
