Now Trafodion can work with openJDK 1.7 and SunJDK 1.7, both are fine, so I assume it will remain same in 1.8, but we have to test, hard to say now.
It seems HBase support JDK 1.8 from newly released HBase 1.2. And Trafodion is now working on HBase 0.98 and Trafodion 2.0 will support HBase 1.1, but since HBase API stay compatible after HBase 1.0, so moving to HBase 1.2 should take less effort than before. But IMHO, HBase 1.1 cannot run with JDK 1.8? If that is correct, I think we cannot change to JDK 1.8, since Trafodion have some coprocessor to be loaded by HBase RS, I assume a jar built with JDK 1.8 may have problems to be loaded by a Java program built with JDK 1.7. But if Trafodion 2.0 can support HBase 1.2, I think move to JDK 8 will be a good idea. But that is not what we originally planned (HBase 1.2), so maybe this will postpone the release of Trafodion 2.0? So need Steve to consider it more. But I strongly vote to Pierre that Trafodion should start planning for JDK 8. Currently, Trafodion java src code cannot directly built with JDK 8, I remember Nitin once gave a very good suggestion to change an java build option, I would like to follow Nitin's suggestion and do some initial investigation. JDK change should be a major change, need more careful consideration of all. We should understand all side effort of it before we can made the change. The major concern is compatibility of various components, not only Trafodion, but also HDFS, HBase, Zookeeper, Hive, etc... If all are moved to JDK 8, Trafodion should follow of course.
