HBASE 错误：无法识别的 VM 选项“UseConcMarkSweepGC”

Question

I have jdk-15.0.1 on my laptop, and have installed HBASE (hbase-2.2.6 version).

I followed every steps to install HBASE on this link: https://www.learntospark.com/2020/08/setup-hbase-in-windows.html

The problem is that when I try running HBASE in my command line using:

start-hbase.cmd 

I get the following error message:

Unrecognized VM option 'UseConcMarkSweepGC'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
ERROR: Could not determine the startup mode.

As a beginner, I tried scouring around for information, but nothing that matches my problem.

I would be glad for any help you could give me.

Answer 1

CMS garbage collector is removed in JDK 15, thus UseConcMarkSweepGC too is removed.

JEP 363: Remove the Concurrent Mark Sweep GC

So, either you should switch back to java 8 or 11, or you should modify below line:

set HBASE_OPTS="-XX:+UseConcMarkSweepGC" "-Djava.net.preferIPv4Stack=true" 

with

set HBASE_OPTS="-Djava.net.preferIPv4Stack=true"
