Attila Doroszlai updated HDDS-2259:
-----------------------------------
Description:
Chunk checksum verification fails for (almost) any file. This is caused by
computing checksum for the entire buffer, regardless of the actual size of the
chunk.
{code:title=https://github.com/apache/hadoop/blob/55c5436f39120da0d7dabf43d7e5e6404307123b/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/keyvalue/KeyValueContainerCheck.java#L259-L273}
byte[] buffer = new byte[cData.getBytesPerChecksum()];
...
v = fs.read(buffer);
...
bytesRead += v;
...
ByteString actual = cal.computeChecksum(buffer)
.getChecksums().get(0);
{code}
This results in marking all closed containers as unhealthy.
