Traceback while trying to launch Presto

Question

I am trying to launch Presto by entering the following in the terminal:

sudo bin/launcher start

It shows me this:

Started as 16501 (This integer varies on every attempt)

Then, I tried to launch it by entering the following in terminal:

sudo bin/launcher run --verbose

The output I get is:

I am unable to understand the error message. Any help would be appreciated.

Here is the config.properties file:

coordinator=true
node-scheduler.include-coordinator=true
http-server.http.port=3306
query.max-memory=2GB
query.max-memory-per-node=1GB
discovery-server.enabled=true
discovery.uri=http://localhost:3306

EDIT: After entering sudo bin/launcher start into the terminal and then sudo bin/launcher status , it says "Not running". Also there is no web page at localhost:3306. If it started successfully, then I should get a web page.

Since I got it fixed myself, I will answer my own question for anyone who encounters this issue in future and comes across this question.

Where exactly was the problem: JRE. (Thanks to kokosing for pointing out that there might be some problem with java)

What I did before: I downloaded jre-8u171-linux-x64.tar.gz from https://java.com/en/download/help/linux_x64_install.xml, placed it in a partition or "media" different from where ubuntu is installed. I configured the .bashrc myself and added the following lines:

JAVA_HOME=/media/polly/161813A518138343/Java/jdk-10.0.1
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
export JAVA_HOME
export JRE_HOME
export PATH

For changes to take place, I executed exec bash in terminal. To check if it was running I tried java -version and it displayed the version of java running. I tried to launch Presto, it wouldn't run.

What I did after: I removed the part that I had added to .bashrc. I used the command sudo apt-get install default-jre. After successful installation I entered java -version and it showed me the version of java installed and running. I tried to launch presto and it ran successfully. I am able to see the page at localhost:3360.
