The v1 patch addresses Jing's comments.
I've tested the patch in all four combinations of secure and HA setups. I've
verified this patch by using WebHDFS to retrieve the content of a file.

Jing Zhao commented on HDFS-6100:
-
The patch looks pretty good to me. Some minor comments:
# In DatanodeWebHdfsMethods, the current patch has some inconsistent field name
for the NamenodeAddressParam parameter (nnId, namenodeId, and
namenodeRpcAddress). How about just calling them "namenode" since it can be
either NameService ID or NameNode RPC address?
# Nit: the following code needs some reformat:
{code}
tokenServiceName = HAUtil.isHAEnabled(conf,
nsId) ? nsId : NetUtils.getHostPortString
(rpcServer.getRpcAddress());
{code}
# In the new unit test, we can add some extra check about the content of the
new created file. Also, maybe we can try to transition the second NN to active
first so that the first create call can also hit a failover.
# Looks like the patch also fixes the token service name in HA setup for
webhdfs. Please update the description of the jira.
# Could you also post your system test results (HA, non-HA, secured, insecure
setup etc.)?

[jira] [Commented] (HDFS-6100) DataNodeWebHdfsMethods does not failover in HA mode

The v0 patch overloads the meaning of the URL parameter {{namenoderpcaddress}}.
It is the host-port pair of the NN in non-HA mode, but it becomes the
nameservice id in HA mode.
