Chris Trezzo commented on HADOOP-13052: --------------------------------------- Adding 2.6.5 to the target versions with the intention of backporting this to branch-2.6. Please let me know if you think otherwise. Thanks! > 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) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
