Cassandra 3.0 and later require Java 8u40 or later

Question

I'm trying to run cassandra 3.0 in datastax. But i'm getting an error saying Cassandra 3.0 and later require Java 8u40 or later.

I have installed java and moved the jdk1.8.0_65 to /usr/local/java and set JAVA_HOME to /usr/local/java/jdk1.8.0_65.

But I'm still facing the following error:

Cassandra 3.0 and later require Java 8u40 or later.

Answer 1

I installed Cassandra 3.2 DataStax Distribution rpm on CentOS 7, and experienced the same problem. Cassandra startup script /etc/rc.d/init.d/cassandra finds java binary in the predefined path list only.

JVM_SEARCH_DIRS="/usr/lib/jvm/jre /usr/lib/jvm/jre-1.7.* /usr/lib/jvm/java-1.7.*/jre"

If your java binary is /usr/jdk64/jdk1.8.0_60/jre/bin/java, append /usr/jdk64/jdk1.8.0_60/jre to JVM_SEARCH_DIRS, or make /usr/lib/jvm/jre symlink for /usr/jdk64/jdk1.8.0_60/jre.

Answer 2

Check your java version. if your Java version is "1.8.0_40" later. goto this file apache-cassandra-3.7\conf\cassandra-env.ps1 and search this word JVM_VERSION.CompareTo("1.8.0_40") then change to your version. For example if you use java 1.8.0_102 then change to JVM_VERSION.CompareTo("1.8.0_102").

Now, check. It will work.

Answer 3

I typically solve this by adding my specific JAVA_HOME into the $DSE_DIR/resources/cassandra/conf/cassandra.in.sh and $DSE_DIR/bin/dse.in.sh scripts provided with DataStax.
Add: JAVA_HOME=/usr/local/java/jdk1.8.0_65 in each. (Or a symlink, if you want to be able to swap the JVM without re-editing these files.)

Answer 4

The following works for me on a RHEL system:

yum install java-1.8.0-openjdk
ln -nfs /usr/lib/jvm/jre-1.8.0-openjdk.x86_64 /etc/alternatives/jre
ln -nfs /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java /etc/alternatives/java

Answer 5

I also have same problem. My solution is editing file apache-cassandra-3.7/bin/cassandra. Below line that contain "#!/bin/sh" (2nd line) you can put line like below

JAVA_HOME="/path/of/your/jdk"

example :

JAVA_HOME="/opt/jdk1.8.0_101"

Hope this solution can help you and other people

Answer 6

1. Check first version of java using this command java -version
2. Check path of java using this command echo $JAVA_HOME

Answer 7

Use following commands.

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

Answer 8

The nodetool might still be accessing the earlier java version, I too faced the same issue.

short do this

sudo vim /etc/environment add this line JAVA_HOME="/usr/lib/jvm/java-8-oracle/jre/bin/java"

source /etc/environment

echo $JAVA_HOME

nodetool status

long do this

Please follow the steps here to install and change the version of java installed in your system . Its explained very well.

Answer 9

Try to use alternatives command:

$ nodetool
Cassandra 3.0 and later require Java 8u40 or later.
$ java -version
java version "1.7.0_151"

$ sudo yum install java-1.8.0-openjdk
... 
$ sudo alternatives --config java

There are 2 programs which provide 'java'.

Selection    Command
-----------------------------------------------
*+ 1           /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java
2           /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java

Enter to keep the current selection[+], or type selection number: 2

$ java -version
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)
$ nodetool
usage: nodetool [(-p <port> | --port <port>)]
    [(-pwf <passwordFilePath> | --password-file <passwordFilePath>)]
    [(-h <host> | --host <host>)] [(-u <username> | --username <username>)]
    [(-pw <password> | --password <password>)] <command> [<args>]

Answer 10

it seems, as if the cassandra service would pick up the Java version from alternatives, only.

sudo alternatives --config java

... don't select Java 9 there.

sudo service cassandra start

/etc/cassandra/default.conf/jvm.options has further JVM parameters.
