> Key: HDFS-16422
> URL: https://issues.apache.org/jira/browse/HDFS-16422
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: dfsclient, ec, erasure-coding
> Affects Versions: 3.3.0, 3.3.1
> Reporter: daimin
> Assignee: daimin
> Priority: Critical
> Labels: pull-request-available

> Reading data on an erasure-coded file with missing replicas(internal block of
> block group) will cause online reconstruction: read dataUnits part of data
> and decode them into the target missing data. Each DFSStripedInputStream
> object has a RawErasureDecoder object, and when we doing pread concurrently,
> RawErasureDecoder.decode will be invoked concurrently too.
> RawErasureDecoder.decode is not thread safe, as a result of that we get wrong
> data from pread occasionally.
