-------------------------------------------
Thanks [[email protected]]. Here are the test results (region: S3 bucket in
U.S east. Tests were run from my laptop). Errors are due to socket time outs
(180 seconds). Checked ITestS3AContractGetFileStatus.teardown, which was again
due to socket timeout.

Results :

> S3A: Consider avoiding array copy in S3ABlockOutputStream (ByteArrayBlock)

> Project: Hadoop Common
> Issue Type: Sub-task

> Reporter: Rajesh Balamohan

>
> In {{S3ADataBlocks::ByteArrayBlock}}, data is copied whenever {{startUpload}}
> is called. It might be possible to directly access the byte[] array from
> ByteArrayOutputStream.
> Might have to extend ByteArrayOutputStream and create a method like
> getInputStream() which can return ByteArrayInputStream. This would avoid
> expensive array copy during large upload.
