Subject [jira] [Updated] (HDFS-11580) Ozone: Support asynchronus client API for SCM and containers
Date Wed, 26 Jul 2017 20:30:00 GMT

     [ https://issues.apache.org/jira/browse/HDFS-11580?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chen Liang updated HDFS-11580:
------------------------------
    Attachment: HDFS-11580-HDFS-7240.010.patch

Post v010 patch to save some iteration time, since I think [~linyiqun] is in a different time
zone. Please review.

Also realized that there were double async in earlier patch. i.e. {{sendCommandAsync}} is
asynchronously calling {{sendCommand}}, then commands are again asynchronously calling {{sendCommandAsync}}.
Instead we can have just one, that is commands asynchronously calling {{sendCommand}}. Which
is what comes with [~nandakumar131]'s suggestion. So I removed  {{sendCommandAsync}} API in
v010 patch too.

> 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.
