At present, all YARN clusters adopt JAVA 7 environment. While trying to use FLINK to handle the deployment of flow processing business scenarios, it was found that FLINK ON YARN mode always failed to perform a session task. The application log of YARN shows Unsupported major. minor version 52.0.
I tried to add env. java. home: < JDK 1.8PATH > in flink-conf. yaml of the mailing list solution. And the startup command adds -yD yarn. taskmanager. env. JAVA_HOME= < JDK1.8PATH>、-yD containerized. master. env. JAVA_HOME= < JDK1.8PATH>, -yD containerized. taskmanager. env. JAVA_HOME= < JDK1.8PATH>. Flink session cluster in YARN can not run Application in JAVA 8 environment. So can I use Flink1.7.X submit Flink session cluster application in YARN under JAVA 7 environment?
