Chris Nauroth commented on HDFS-5358:
-------------------------------------
Can we use uint32 for replication in the protocol? This would further prevent
a negative value, and also it would be consistent with the replication field in
other protocol messages. (See example below.)
Aside from that, the patch looks good.
{code}
message SetReplicationRequestProto {
required string src = 1;
required uint32 replication = 2; // Short: Only 16 bits used
}
{code}
> add 'replication' field to PathBasedCacheDirective
