Subject [jira] [Updated] (HDFS-12450) Fixing TestNamenodeHeartbeat and support non-HA
Date Fri, 15 Sep 2017 18:21:01 GMT

     [ https://issues.apache.org/jira/browse/HDFS-12450?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Chris Douglas updated HDFS-12450:
    Attachment: HDFS-12450-HDFS-10467.001.patch

bq. Not sure I agree with FindBugs regarding the keyset().
It's being pedantic about the redundant lookups, but I think it's avoidable.

> The way the service RPC address is obtained changed and showed a problem with {{TestNamenodeHeartbeat}}
where the address wasn't properly set for the unit tests.
> In addition, the {{NamenodeHeartbeatService}} did not provide a good experience for non-HA
nameservices. This also covers a better logging for those.
