>                 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.
