[jira] [Commented] (HDDS-5151) Support ByteBuffer read in OzoneInputStream

    [ https://issues.apache.org/jira/browse/HDDS-5151?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17338747#comment-17338747 ] 

Wei-Chiu Chuang commented on HDDS-5151:
---------------------------------------

It is used when Impala can't use short circuit read (which we don't have now). So yeah, useful for reading from a remote storage (HDFS, S3A...)
