Íñigo Goiri commented on HDFS-13857:
Thanks for [^HDFS-13857.003.patch].
We still need a test for the cases when
{{assertFalse(mountTable.isDefaultNSRWEnable());}}.
A minor nit, we could call the variable DFS_ROUTER_DEFAULT_NAMESERVICE_ENABLE
and default.nameservice.enable without RW.

[jira] [Commented] (HDFS-13857) RBF: Choose to enable the default nameservice to write files.

I think we still need the false case unit test where we expect the new exception because the path is not defined. We would have a mount point in say /a, this should succeed, then when testing /, we should get an exception. > RBF: Choose to enable the default nameservice to write files. > - > > Key: HDFS-13857 > URL: https://issues.apache.org/jira/browse/HDFS-13857 > Project: Hadoop HDFS > Issue Type: Improvement > Components: federation, hdfs >Affects Versions: 3.0.0, 3.1.0, 2.9.1 >Reporter: yanghuafeng >Assignee: yanghuafeng >Priority: Major > Attachments: HDFS-13857.001.patch, HDFS-13857.002.patch > > > The default nameservice can provide some default properties for the namenode > protocol.

Íñigo Goiri commented on HDFS-13857:
Thanks [~hfyang20071] for the patch.
I'm not sure the implementation in [^HDFS-13857.001.patch] is onyl for writes
as it will also disallow reads.
I'm fine with that but we need to rename everything accordingly.
Some other comments:
* We could throw the exception in the lookup itself and then just add if
(!defaultNSWriteEnable) throw new IOException("Cannot find locations for " +
path);
* The message could be a little more specific in this case and say we don't
support this because the default is not enabled.
* We should have the false unit test too.
* The change with FEDERATION_MOUNT_TABLE_MAX_CACHE_SIZE should be avoided to
reduce churn.
