But my doubt is this? Why we have a problem with it? Things should work with out using Unsafe ways. We may miss some possible optimization but no issues/failures any where. That means some thing is wrong in FuzzyRowFilter and/or its tests? We should address that also? > UnsafeAvailChecker wrongly returns false on ppc > ----------------------------------------------- > > Key: HBASE-17869 > URL: https://issues.apache.org/jira/browse/HBASE-17869 > Project: HBase > Issue Type: Bug > Affects Versions: 1.2.4 > Reporter: Jerry He > Assignee: Jerry He > Priority: Minor > Fix For: 2.0.0, 1.4.0 > > Attachments: HBASE-17869.patch > > > On ppc64 arch, java.nio.Bits.unaligned() wrongly returns false due to a JDK bug. > https://bugs.openjdk.java.net/browse/JDK-8165231 > This causes some problem for HBase. i.e. FuzzyRowFilter test fails. > Fix it by providing a hard-code workaround for the JDK bug. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
