Druid requires Java 8, 11, or 17. $current_version_text
|
|
|
|
If you believe this check is in error, or you want to proceed with a potentially
|
|
unsupported Java runtime, you can skip this check using an environment variable:
|
|
|
|
export DRUID_SKIP_JAVA_CHECK=1
|
|
|
|
Otherwise, install Java 8, 11, or 17 in one of the following locations.
|
|
|
|
* DRUID_JAVA_HOME
|
|
* JAVA_HOME
|
|
* java (installed on PATH)
|
|
|
|
Other versions of Java versions may work, but are not officially supported.
|
