> DistCp result has data and checksum mismatch when blocks per chunk > 0
> ----------------------------------------------------------------------
>
> Key: HADOOP-16049
> URL: https://issues.apache.org/jira/browse/HADOOP-16049
> Project: Hadoop Common
> Issue Type: Bug
> Components: tools/distcp
> Affects Versions: 2.9.2
> Reporter: Kai Xie
> Assignee: Kai Xie
> Priority: Major
> Attachments: HADOOP-16049-branch-2-001.patch,
> HADOOP-16049-branch-2-002.patch, HADOOP-16049-branch-2-003.patch
>
>
> In 2.9.2 RetriableFileCopyCommand.copyBytes,
> {code:java}
> int bytesRead = readBytes(inStream, buf, sourceOffset);
> while (bytesRead >= 0) {
> ...
> if (action == FileAction.APPEND) {
> sourceOffset += bytesRead;
> }
> ... // write to dst
> bytesRead = readBytes(inStream, buf, sourceOffset);
> }{code}
> it does a positioned read but the position (`sourceOffset` here) is never
> updated when blocks per chunk is set to > 0 (which always disables append
> action). So for chunk with offset != 0, it will keep copying the first few
> bytes again and again, causing result to have data & checksum mismatch.
> To re-produce this issue, in branch-2, update BLOCK_SIZE to 10240 (> default
> copy buffer size) in class TestDistCpSystem and run it.
> HADOOP-15292 has resolved the issue reported in this ticket in
> trunk/branch-3.1/branch-3.2 by not using the positioned read, but has not
> been backported to branch-2 yet
