Todd Lipcon commented on HDFS-2618:
-----------------------------------
{code}
- required BlockProto block = 1; // Block
- repeated DatanodeIDProto datanodeIDs = 2; // Datanodes with replicas of the
block
+ required BlockProto block = 1; // Block
+ repeated string datanodeIDs = 2; // Datanodes with replicas of the block
{code}
What's the reason for this change? Encapsulating the DNIDs has the nice
property that if we want to add extra flags about each location, it would be a
simple non-breaking change.
