[jira] [Commented] (HDDS-2703) OzoneFSInputStream to support ByteBufferReadable

    [ https://issues.apache.org/jira/browse/HDDS-2703?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16995169#comment-16995169 ] 

YiSheng Lien commented on HDDS-2703:
------------------------------------

Note:
Cause the current dependency version of Hadoop in Ozone is 3.2.0, 

I don't implement {{ByteBufferPositionedReadable}}  for now. (Supported in Hadoop 3.3.0)

The same is {{StreamCapabilities}}, the {{StreamCapabilities}} support {{StreamCapabilities.READBYTEBUFFER}} for Hadoop 3.3.0 now.

Should we create a JIRA for these ?

> ByteBufferReadable could help certain application performance, such as Impala. (See HDFS-14111)
> Additionally, if we support ByteBufferPositionedReadable, it would benefit HBase. (see HDFS-3246)
> Finally, we should add StreamCapabilities to let client probe for these abilities. (See HDFS-11644)
