Todd Lipcon updated HDFS-2861:
------------------------------
Attachment: hdfs-2861.txt
New revision addresses the following:
- now that we have a few more sanity checks during startup, I ran into issues
where, when the sanity checks failed, the shutdown process of FSN threw NPEs
since other members were still null. Added null checks.
- The HA tests were previously using a null nameservice ID, which isn't
actually valid. The new config checks were failing with that. So now, it always
sets up a nameservice ID for HA clusters. MiniDFSCluster then needs to
propagate that to the DFS_FEDERATION_NAMESERVICES config.
- TestDFSUtil.testSubstituteForWildcardAddress was failing in the context of
the whole suite since another test in that suite was enabling kerberos support
in UGI. Added a @Before which resets UGI.
I ran all the unit tests with this patch and they passed.
> HA: checkpointing should verify that the dfs.http.address has been configured

> In an HA setup I was running for the past week, I just noticed that
> checkpoints weren't getting properly uploaded, since the SBN was connecting
> to http://0.0.0.0:50070/ rather than the correct dfs.http.address. So, it was
> uploading checkpoints to itself instead of the peer. We should add sanity
> checks during startup to ensure that the configuration is correct.
