HDFS-4660 fixed a data corruption issue and HDFS-8722 fixed a performance regression in HDFS-4660. These changes introduced this bug (HDFS-9220). So, if you want to fix the corruption issue, you need to pull in all three. The issue fixed in HDFS-4660 was originally seen very rarely, but after the datanode layout change, it was occurring much more frequently along with other bugs we fixed regarding pipeline failures. If you plan to pull in the layout fix in the next release of 2.6, HDFS-4660 may not be as critical. > Reading small file (< 512 bytes) that is open for append fails due to > incorrect checksum > > > Key: HDFS-9220 > URL: https://issues.apache.org/jira/browse/HDFS-9220 > Project: Hadoop HDFS > Issue Type: Bug >Affects Versions: 2.7.1 >Reporter: Bogdan Raducanu >Assignee: Jing Zhao >Priority: Blocker > Fix For: 3.0.0, 2.7.2 > > Attachments: HDFS-9220.000.patch, HDFS-9220.001.patch, > HDFS-9220.002.patch, test2.java > > > Exception: > 2015-10-09 14:59:40 WARN DFSClient:1150 - fetchBlockByteRange().

--
Test failures seem unrelated. They failed due to
{{java.lang.NoClassDefFoundError}}, {{Port in Use}}, etc., which are test
runtime issue.

As the javadoc says, when offset==end, there is no more checksum to write thus
the lastCrc should be set to crcBytes.

Daniel Templeton commented on HDFS-9220:
Thanks, [~jingzhao]. Could you add some comments to the patch to make it a
little more clear what the test is doing? Something like:
{code}
// Reading in data from the small block. If the checksum is wrong, the read
will throw an exception. If it doesn't, the checksum is correct.
{code}
I'd also love a blank line before the try to make it easier on the eyes.
