Colin Patrick McCabe created HDFS-3889: ------------------------------------------ Summary: distcp silently ignores missing checksums Key: HDFS-3889 URL: Project: Hadoop HDFS Issue Type: Bug Components: tools Affects Versions: 2.2.0-alpha Reporter: Colin Patrick McCabe Priority: Minor If distcp can't read the checksum files for the source and destination files-- for any reason-- it ignores the checksums and overwrites the destination file. It does produce a log message, but I think the correct behavior would be to throw an error and stop the distcp. If the user really wants to ignore checksums, he or she can use {{-skipcrccheck}} to do so. The relevant code is in DistCpUtils#checksumsAreEquals: {code} try { sourceChecksum = sourceFS.getFileChecksum(source); targetChecksum = targetFS.getFileChecksum(target); } catch (IOException e) { LOG.error("Unable to retrieve checksum for " + source + " or " + target, e); } {code} -- This message is automatically generated by JIRA.
