> Read multiple chunks directly from FSInputChecker subclass into user buffers
> ----------------------------------------------------------------------------

> Key: HADOOP-3205
> URL: https://issues.apache.org/jira/browse/HADOOP-3205
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Reporter: Raghu Angadi

>
> Implementations of FSInputChecker and FSOutputSummer like DFS do not have
> access to full user buffer. At any time DFS can access only up to 512 bytes
> even though user usually reads with a much larger buffer (often controlled by
> io.file.buffer.size). This requires implementations to double buffer data if
> an implementation wants to read or write larger chunks of data from
> underlying storage.
> We could separate changes for FSInputChecker and FSOutputSummer into two
> separate jiras.
