> Consolidate client striping input stream codes for stateful read and
> positional read
> ------------------------------------------------------------------------------------
>
> Key: HDFS-8957
> URL: https://issues.apache.org/jira/browse/HDFS-8957
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: erasure-coding
> Reporter: Kai Zheng
> Assignee: Youwei Wang
> Attachments: HDFS-8957-v1.patch, HDFS-8957.v2.patch,
> HDFS-8957.v3.patch, HDFS-8957.v4.patch
>
>
> Currently we have different implementations for client striping read, having
> both *StatefulStripeReader* and *PositionStripeReader*. I attempted to
> consolidate the two implementations into one, and it results in much simpler
> codes, and also better performance. Now in both read paths, it will:
> * Use pooled ByteBuffers, as currently stateful read does;
> * Read directly into application's buffer, as currently positional read does;
> * Try to align and merge multiple stripes, as currently positional read does;
> * Use *ECChunk* version decode API.
> The resultant *StripeReader* is approaching very near now to the ideal state
> desired by next step, employing *ErasureCoder* API instead of
> *RawErasureCoder* API.
> Will upload an initial patch to illustrate the rough change, even though it
> depends on other issues.
