Re: Re: Can HBase 2.5.8 working with jdk17?

[Reid Chan]

should be able to run on JDK17

I think, at least, you need to provide your error logs, and related
environment variables.

I can’t answer that because I know nothing about your environment or the
error you are receiving. For us it just worked to start up. You may have to
change jvm flags in your hbase-env.sh if you are using old deprecated flags
that may be removed in jdk17.

Re: Can HBase 2.5.8 working with jdk17?

[Bryan Beaudreault]

We ran hbase under jdk17 for a few months. The only issue we saw was
https://issues.apache.org/jira/browse/HBASE-28206 which was fixed in 2.5.7.

More recently we’ve upgraded again to jdk21 to gain access to generational
zgc. That also has been working fine without any additional patches.

We’re running with hdfs 3.3.6, which may or may not matter.
