Brandon Li commented on HDFS-4340:
----------------------------------
{quote}what is the reason for adding default value to the field?{quote}
The default value 0 is considered as invalid fileId. The valid fileId(inodeId)
is starting from 1001. The server knows the client is an old client and thus
will skip some fileId checkings. I will add the comment in .proto file and
update the javadoc for INodeId class to make it clearer. Thanks!
> Update addBlock() to inculde inode id as additional argument
