Subject [jira] [Commented] (HDFS-10351) Ozone: Optimize key writes to chunks by providing a bulk write implementation in ChunkOutputStream.
Date Mon, 02 May 2016 18:07:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15267127#comment-15267127
] 

Chris Nauroth commented on HDFS-10351:
--------------------------------------

The failure in {{TestStorageContainerManager}} is unrelated to this patch.  There is a problem
that needs to be fixed though with control of the bound network address used by the container
server.  It goes far out of the scope of this issue, so I filed HDFS-10356 to track that separately.

[~anu] and [~jingzhao], what do you think of patch v003?

> HDFS-10268 introduced the {{ChunkOutputStream}} class as part of end-to-end integration
of Ozone receiving key content and writing it to chunks in a container.  That patch provided
an implementation of the mandatory single-byte write method.  We can improve performance by
adding an implementation of the bulk write method too.
