Hudson commented on HADOOP-13052: --------------------------------- FAILURE: Integrated in Hadoop-trunk-Commit #9657 (See [https://builds.apache.org/job/Hadoop-trunk-Commit/9657/]) HADOOP-13052. ChecksumFileSystem mishandles crc file permissions. (kihwal: rev 9dbdc8e12d009e76635b2d20ce940851725cb069) * hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/ChecksumFileSystem.java * hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/fs/TestChecksumFileSystem.java > ChecksumFileSystem mishandles crc file permissions > -------------------------------------------------- > > Key: HADOOP-13052 > URL: https://issues.apache.org/jira/browse/HADOOP-13052 > Project: Hadoop Common > Issue Type: Bug > Components: fs > Affects Versions: 2.7.0 > Reporter: Daryn Sharp > Assignee: Daryn Sharp > Fix For: 2.7.3 > > Attachments: HADOOP-13052.patch > > > CheckFileSystem does not override permission related calls to apply those > operations to the hidden crc files. Clients may be unable to read the crcs > if the file is created with strict permissions and then relaxed. > The checksum fs is designed to work with or w/o crcs present, so it silently > ignores FNF exceptions. The java file stream apis unfortunately may only > throw FNF, so permission denied becomes FNF resulting in this bug going > silently unnoticed. > (Problem discovered via public localizer. Files are downloaded as > user-readonly and then relaxed to all-read. The crc remains user-readonly) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
