Anu Engineer commented on HDFS-11582:
-------------------------------------

[~vagarychen] Thank you for updating the patch. Two minor comments.
* CBlockTargetServer.java
Nit: Typo : {{fllushListenerThread}} ==> flushListenerThread

* The user string seems to be same for two different keys.
{code}
public static final String OZONE_SCM_CLIENT_PORT_KEY =
      "ozone.scm.client.port";
  public static final int OZONE_SCM_CLIENT_PORT_DEFAULT = 9860;
  public static final String OZONE_SCM_DATANODE_PORT_KEY =
      "ozone.scm.client.port";
  public static final int OZONE_SCM_DATANODE_PORT_DEFAULT = 9861;

> This JIRA adds the daemon process that exposes SCSI target access. More specifically,
with this daemon process running, any OS with SCSI can talk to this daemon process and treat
CBlock volumes as SCSI targets, in this way the user can mount the volume just like the POSIX
manner.
