alluxio

setting up Alluxio cluster, path points to Java 8 but Alluxio thinks it's java 7?

I am setting up an Alluxio cluster. I ran the script ./bin/alluxio-start.sh all SudoMount, but got this error Error: Alluxio requires Java 8 or Java 11, currently Java 1.7.0_321 found. I already set JAVA_HOME and add it to $PATH to point to Java 8. Why does Alluxio still think it is java 7?

$$echo $JAVA_HOME
/usr/lib/jvm/java-1.8.0-openjdk-amd64
…$ java -version
openjdk version “1.8.0_322”
Solution

  • run this and see what’s the output: sudo update-alternatives --display java if it’s linked to 1.7 then you can use following command to set it to 1.8 sudo update-alternatives --config java
