Hi Evgeny, thanks for you interest in Apache Pinot.
First of all, I have to say that Apache Pinot 1.0.0 should work in Java 21, but it is still not officially supported. Next release (1.1.0) will bring official support. Also, as a recommendation, it seems you are using OpenJDK 21, which is not recommended for production usage. Instead it is recommended (not by the Pinot team, but the Java community in general) to use other distributions like Eclipse Temurin, Microsoft JDK, Oracle JDK, Azul OpenJDK, Amazon Corretto, etc.
Anyway, as said, although we don't officially support Java 21, Apache Pinot should run in there. I've downloaded the binary from the web and executed in the same way you did in Linux and didn't have that issue. By the way, have you tried to execute Pinot with other JDK (specially Java 11)? did it work?
Given your bash reports an error in line 203 of pinot-admin, which is:
```bash
if [ "$(jdk_version)" -gt 11 ]; then
```
I would say the error is in `jdk_version` bash function, which tries to detect your jvm version in order to modify JAVA_OPTS accordingly.
That script is defined as
```bash
jdk_version() {
IFS='
'
# remove \r for Cygwin
lines=$(java -Xms32M -Xmx32M -version 2>&1 | tr '\r' '\n')
for line in $lines; do
if test -z $result && echo "$line" | grep -q 'version "'
then
ver=$(echo $line | sed -e 's/.*version "\(.*\)"\(.*\)/\1/; 1q')
# on macOS, sed doesn't support '?'
if case $ver in "1."*) true;; *) false;; esac;
then
result=$(echo $ver | sed -e 's/1\.\([0-9]*\)\(.*\)/\1/; 1q')
else
result=$(echo $ver | sed -e 's/\([0-9]*\)\(.*\)/\1/; 1q')
fi
fi
done
unset IFS
echo "$result"
}
```
Given you included your `java --version` in the report, I've modified the script to use your `java --version` and it correctly returned `21` for me. So I'm not sure where is the issue.
Can you modify your copy of `bin/pinot-admin.sh` to add `set -x` to the first line of `jdk_version` function? It should be something like:
```bash
jdk_version() {
set -x
IFS='
'
# remove \r for Cygwin
lines=$(java -Xms32M -Xmx32M -version 2>&1 | tr '\r' '\n')
for line in $lines; do
if test -z $result && echo "$line" | grep -q 'version "'
then
ver=$(echo $line | sed -e 's/.*version "\(.*\)"\(.*\)/\1/; 1q')
# on macOS, sed doesn't support '?'
if case $ver in "1."*) true;; *) false;; esac;
then
result=$(echo $ver | sed -e 's/1\.\([0-9]*\)\(.*\)/\1/; 1q')
else
result=$(echo $ver | sed -e 's/\([0-9]*\)\(.*\)/\1/; 1q')
fi
fi
done
unset IFS
echo "$result"
}
```
Once you execute with that script you should see something like:
```
> bin/pinot-admin.sh StartController -zkAddress 172.16.0.23:2181 -controllerHost 172.16.0.23 -controllerPort 9777 -dataDir /usr/local/pinot/data/controller -clusterName cluster-prod
++ IFS='
'
+++ java -Xms32M -Xmx32M -version
+++ tr '\r' '\n'
++ lines='openjdk version "21" 2023-09-19 LTS

++ for line in $lines
++ test -z
++ echo 'openjdk version "21" 2023-09-19 LTS'
++ grep -q 'version "'
+++ echo 'openjdk version "21" 2023-09-19 LTS'
+++ sed -e 's/.*version "\(.*\)"\(.*\)/\1/; 1q'
++ ver=21
++ case $ver in
++ false
+++ echo 21
+++ sed -e 's/\([0-9]*\)\(.*\)/\1/; 1q'
++ result=21
++ for line in $lines
++ test -z 21
++ for line in $lines
++ test -z 21
++ unset IFS
++ echo 21
SLF4J: Class path contains multiple SLF4J bindings.
...
```
Which should give us more information about the issue.
