Subject [jira] [Created] (HDFS-12183) Ozone: KSM : Use proper defaults for block client address

-----------------------------------

             Summary: Ozone: KSM :  Use proper defaults for block client address
                 Key: HDFS-12183
                 URL: https://issues.apache.org/jira/browse/HDFS-12183
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: ozone
    Affects Versions: HDFS-7240
            Reporter: Anu Engineer
            Priority: Trivial
             Fix For: HDFS-7240


The setting *ozone.scm.block.client.address* allows extra flexibility but it is set to the
*ozone.scm.client.address* all the time when we deploy the cluster.

Currently, KSM will fail to startup if *ozone.scm.block.client.address* is not configured.
This JIRA suggests that we use *ozone.scm.client.address* as the default for the *ozone.scm.block.client.address*,
so we don't have to explicitly configure *ozone.scm.block.client.address*.

Change involves modifying *getScmAddressForBlockClients* and the passing the default parameter
to *getHostNameFromConfigKeys* and *getPortNumberFromConfigKeys*
