You are a savior! Spent 8 hours trying to troubleshoot something yesterday and after watching your video I realized it was a path issue. Everything is working like a charm. Thanks for doing this walkthrough!

[@ronobloom2752]

Suggestion: May be update the video with the latest Cassandra and its changes, if you have time. Really awesome tutorial. Simple and to the point!!!

[@anujkalra6145]

Actually, all his steps are listed in the Cassandra Linux Installation Guide. Aside from installing Java, everything can be followed from there. Link is in the description.

[@V4riousMind]

i got that problem as well and searched a lot for fixes. i recently deinstalled openjdk-11-jdk-headless and installed openjdk-8-jdk-headless and since then everything works fine. maybe this helps you.

@@V4riousMind I used openjdk-8, and cassandra version 40. i got active status=exited. has anything changed, i know its been a year?

[@V4riousMind]

@@jubrilbabatunde3040 i actually don't know. i did this for my final exam of my education and since then i never touched it again. (not because boring but i don't have a private use for it) i think, that the older version i used (before 4.0) needed jdk8 but the new 4.0 version needed 11 so i used the older version to get my project done. maybe this helps you. Good Luck :)

Same. Did you find the solution?

[@isaacalexisrivera3157]

​@@amandutta004 i was doing it in an aws ec2 instance and got rejected , when i tried in an virtual machine on google cloud, i could do it. Until today I do not know what was the cause of that failure, finding solutions in google, the mentioned it a trouble with the memsize. stackoverflow.com/questions/51647115/cassandra-nodetool-failed-to-connect-to-127-0-0-17199

This video needs an update, getting running=exited. cant figure out whats wrong, cause there was no error in the process of installation, everything went smooth, till i checked the status of my cassandra instance.

[@NotFamousReal]

Very simple and easy to follow!

[@shikharsingh4162]

I have installed jdk-8 then also it is showing the error:null

Great Tutorial !!! I've been trying to follow the instructions for monitoring the installed cassandra on my Linux Mint 20 distribution but when I type "nodetool status" I get a log error message starting with: Cannot initialize un-mmaper. (Are you using a non-Oracle JVM?) Compacted data files will not be removed promptly. Consider using an Oracle JVM or using standard disk access mode I even tried to setup my java following the exact instructions found on your video but so far I've failed on solving this. Any hint or idea?

[@gaganroshan126]

[@samthou7334]

[@yaseenshaik103]
