Ning Li commented on HADOOP-4271: --------------------------------- I will address the comments in the next patch. > There is already a TestFSInputChecksum.java in hdfs. Can you add this case > there? I see a TestFSInputChecker.java in hdfs. I'll merge the two. But should I move it to fs? Since everything tested is in fs? > Bug in FSInputChecker makes it possible to read from an invalid buffer > ---------------------------------------------------------------------- > > Key: HADOOP-4271 > URL: https://issues.apache.org/jira/browse/HADOOP-4271 > Project: Hadoop Core > Issue Type: Bug > Components: fs > Affects Versions: 0.16.0 > Reporter: Ning Li > Priority: Blocker > Fix For: 0.18.2, 0.19.0, 0.20.0 > > Attachments: .data_testFSInputChecker.crc, data_testFSInputChecker, > hadoop-4271.patch > > > Bug in FSInputChecker makes it possible to read from an invalid buffer.
