> EC: client copy wrong buffer from decode output during pread
> ------------------------------------------------------------
>
> Key: HDFS-16970
> URL: https://issues.apache.org/jira/browse/HDFS-16970
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: dfsclient, ec, erasure-coding
> Affects Versions: 3.3.4
> Reporter: MingHui Luo
> Priority: Critical
> Labels: pull-request-available
> Fix For: 3.4.0, 3.3.5, 3.2.5
>
>
> When dfsStripedInputStream do pread from a striped block group and read
> internal block timeout, so will read parity block for decode and fill
> original chunk buffer with decoded data.
> Here try to fill original chunk buffer with decoded data, but get wrong data.
> The reason is that
> 1.original chunk buffer already read some bytes before timeout from
> blockReader
> 2.chunkBytebuffer's slice always fill begin 0 position of decodeByteBuffer
> slice bytebuffer will fill from wrong decodeByteBuffer position, so will get
> wrong data from pread.
