Subject [jira] [Commented] (HDFS-11580) Ozone: Support asynchronus client API for SCM and containers
Date Tue, 01 Aug 2017 19:00:03 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16109526#comment-16109526
] 

Anu Engineer commented on HDFS-11580:
-------------------------------------

[~vagarychen] The following tests will fail if we enforce non-null or empty trace ID check.
I am going to pass this for time being. We can always file an independent JIRA to fix this
if needed. From the point of view of this JIRA, an empty or null trace ID is valid.
{code}  
  TestContainerMetrics.testContainerMetrics
  TestOzoneContainer.testBothGetandPutSmallFile
  TestOzoneContainer.testCloseContainer
  TestOzoneContainer.testOzoneContainerViaDataNode
  TestOzoneContainer.testXcieverClientAsync
  TestOzoneContainer.testCreateOzoneContainer
  TestOzoneContainer.testDeleteContainer
  TestContainerServer.testClientServer
  TestContainerServer.testClientServerWithContainerDispatcher
  TestKeys.testPutAndGetKeyWithDnRestart

> This is an umbrella JIRA that needs to support a set of APIs in Asynchronous form.
> For containers -- or the datanode API currently supports a call {{sendCommand}}. we need
to build proper programming interface and support an async interface.
> There is also a set of SCM API that clients can call, it would be nice to support Async
interface for those too.
