[jira] [Commented] (HADOOP-12106) JceAesCtrCryptoCodec.java may
have an issue with Cypher.update(ByteBuffer, ByteBuffer)
[ https://issues.apache.org/jira/browse/HADOOP-12106?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14636789#comment-14636789 ]
Tony Reix commented on HADOOP-12106:
------------------------------------
Issue was in the IBM JVM. Some rare and subtle case that was fixed in OpenJDK and not in IBM JVM.

> Key: HADOOP-12106
> URL: https://issues.apache.org/jira/browse/HADOOP-12106
> Project: Hadoop Common
> Issue Type: Bug
> Components: security
> Affects Versions: 2.6.0, 2.7.0
> Environment: Hadoop 2.60 and 2.7+
> - AIX/PowerPC/IBMJVM
> - Ubuntu/i386/IBMJVM
> Reporter: Tony Reix
> Attachments: mvn.Test.TestCryptoStreamsForLocalFS.res20.AIX.Errors, mvn.Test.TestCryptoStreamsForLocalFS.res20.Ubuntu-i386.IBMJVM.Errors, mvn.Test.TestCryptoStreamsForLocalFS.res22.OpenJDK.Errors
>
>
> On AIX (IBM JVM available only), many sub-tests of :
> org.apache.hadoop.crypto.TestCryptoStreamsForLocalFS
> fail:
> Tests run: 13, Failures: 5, Errors: 1, Skipped:
> - testCryptoIV
> - testSeek
> - testSkip
> - testAvailable
> - testPositionedRead
> When testing SAME exact code on Ubuntu/i386 :
> - with OpenJDK, all tests are OK
> - with IBM JVM, tests randomly fail.
> The issue may be in the IBM JVM, or in some Hadoop code that not perfectly handles differences due to different IBM JVM.
