The "HadoopJavaVersions" page has been changed by SomeOtherAccount: http://wiki.apache.org/hadoop/HadoopJavaVersions?action=3Ddiff&rev1=3D19&re= v2=3D20 = Hadoop 0.20.20x, 0.21.0, and trunk use a few Sun-specific APIs which IBM = Java does not provide. [[https://issues.apache.org/jira/browse/HADOOP-6941|= HADOOP-6941]] and [[https://issues.apache.org/jira/browse/HADOOP-7211|HADOO= P-7211]] have been filed to support non-Sun/Oracle Java. = - =3D=3D Apache Harmony =3D=3D - [[http://harmony.apache.org/|Apache Harmony]] is the Java SE project of t= he Apache Software Foundation. Within this project Harmony Select exists as= a lightweight JVM with only a subset (ex. swing, applet and others not inc= luded) of the libraries in Harmony. For the past couple of months we have w= orked on the task of making all three projects in Hadoop run in Harmony Sel= ect 6, there are still a few non critical pending issues in all three proje= cts, but we hope this serves as a useful guide for anyone deciding to use b= oth Harmony and Hadoop. - = - * [[HarmonyBuild|Building Harmony and Harmony Select 6]] - * [[HarmonyCommon|Hadoop common on Harmony Select]] - * [[HarmonyHdfs|Hadoop hdfs on Harmony Select]] - * [[HarmonyMapreduce|Hadoop mapreduce on Harmony Select]] - = =3D=3D A request for help from JVM/JDK developers =3D=3D We would strongly encourage anyone who produces a JVM/JDK to test compili= ng and running Hadoop with it. It makes for a fantastic performance and str= ess test. As Hadoop is becoming a key back-end datacenter application, good= Hadoop support matters. =20
