Cassandra 2.2.1 will not start using cassandra -f

Question

I've downloaded cassandra from apache.cassandra.

I've made sure my env path vars are correctly set.

I type: cassandra -f in a windows command prompt and this is what I get:

E:\apache-cassandra-2.2.1\bin>cassandra -f

E:\apache-cassandra-2.2.1\bin>

this is driving me nuts. I don't understand why this is so difficult.

I'm running on windows 10 pro and have plenty of space. This is on a LAPTOP and this should work, but of course, it is not.

My cassandra.yaml file is fine.

I'm running localhost as my "seed". Should I make it 127.0.0.1, localhost or just the IP of my local machine?

Do I need to adjust my "etc/hosts" file?

Anyone to help would be appreciated.

Answer 1

1. In the: C:\Program Files\apache-cassandra-3.11.3\conf" folder open the file - "cassandra-env.
2. Search for: JAVA_HOME
3. It will show you the path that would be created by the code for java exe file.
4. Double check and make sure that the path is correct.

You can do it by directly updating the file or by updating the Environment variable as explained in other answers.

Answer 2

This might be due to JAVA_HOME env variable that Cassandra points to. The JAVA_HOME environment variable in .ps1 script file points to JAVA_HOME\bin\java.exe, so in your system the environment variable should be excluding "bin", ie, C:\Program Files\Java\jdk1.8.0_172 to avoid the conflict as after JAVA_HOME it appends bin\java.exe in the file automatically.

p.s This is how it worked for me.

Answer 3

You can see a line like this $env:JAVA_BIN = "$env:JAVA_HOME\bin\java.exe in cassandra-env.ps1 inside cassandra\conf folder. This error occurs when JAVA_HOME path is wrong . go to system -> environment variables change to JAVA_HOME to correct path which is jdk folder.

Answer 4

had the same issue. turns out I wasn't running CMD as Admin... :self-face-slap:

Answer 5

I just faced and resolved a similar error when setting up Cassandra 2.1.11. In my case the script was expecting a JAVA_BIN environment variable. Check the .ps1 script and create the missing environment variable JAVA_BIN pointing ...\bin\java.exe.
