Hi Gerald, Now Apache Hadoop supports Java 8 and not support Java 9 or upper.
We've been working for supporting Java 9 and Java 10, - https://issues.apache.org/jira/browse/HADOOP-11123 - https://issues.apache.org/jira/browse/HADOOP-11423 however, Java 9 is now unsupported and Java 10 support will end soon. Therefore we should target only the LTS releases. I'll update the descriptions of the above jira issues. Given Java 8 loses support during January 2019, I'm thinking we need to finish the work for Java 11 LTS support before the date. Java 9 and 10 have many incompatibility for Apache Hadoop and its many dependencies, so it's very tough work. Any help is greatly appreciated!

So with the changes in how Java is released and supported are there going to be any changes in how Hadoop supports Java versions? For those not aware Oracle has changed how Java is supported, with the following details: 1) Java is now on a 6 month release schedule 2) anything other than a LTS release gets dropped as soon as the next version is released. Thus with the release of Java 10 this week that means Java 9 is now unsupported. 3) the next LTS release is Java 11 (due Sept 2018), however LTS is only available by paying Oracle. If you don't pay Oracle than Java 11 loses support when Java 12 is released (scheduled March 2019) 4) Java 8 loses support (no more security fixes, etc.) during January 2019. Summary: - going forward the only way to get the Oracle JRE/JDK is to pay Oracle for the Oracle LTS version - otherwise you get OpenJDK with a 6 month supported window. - the only current option for longer support other than Oracle would be the LTS versions of Linux/BSD distributions. --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
