Rushabh S Shah updated HDFS-12386:
----------------------------------
    Attachment: HDFS-12386-2.patch

{quote}
The FSNameSystem#serverDefaults is statically built to avoid unnecessary 
construction of the object. It would be nice if the json-encoded string was 
cached to avoid unnecessary conversion of a static object into a map and 
serializing into a string.
{quote}
Addressed in latest patch (v2)

{quote}
Not sure -1 is an appropriate value for missing parameters. I'd double check 
the PB defaults for parity with hdfs.
{quote}
For all the required fields, kept the default value as -1.
For all the optional fields, synced with protobuf default values.

{quote}
Default checksum should probably be 0 (represents "none") instead of -1.
{quote}
Actually in protobuf, the default value is 1.

{quote}
Blindly casting relatively new fields like storage policy to a primitive type 
cause exceptions.
{quote}
Added a containsKey check for {{encryptDataTransfer}} value.

{quote}
In the test, it verifies the server defaults returned from hdfs and webhdfs are 
equal. It doesn't verify that one of them actually matches the explicitly conf 
values set by the test.

Addressed in the latest patch (v2)
