Pretty simple once you know how. | |
Step 1: In IntelliJ, create a new remote debug configuration. Name it something ElasticSearchy. All of the default values should be fine. The only thing you need to change is the Host value. If ElasticSearch is gonna be running locally, just use "localhost", otherwise use the IP address of the remote machine ElasticSearch is gonna run on | |
Step 2: When starting ElasticSearch, just add a -D argument with the standard java remote debug values like so: | |
bin/elasticsearch -D "-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005" | |
ElasticSearch will start and if suspend is set to 'y', it'll pause execution until you have attached the IntelliJ debugger. | |
Step 3: In IntilliJ, run the remote debug configuration you created in step 1. | |
At this point any breakpoints you have set in, say, an ElasticSearch plugin will get hit |

I am having issue while starting elasticsearch in debug mode
11:55 AM Tue Oct 10# ls bin/
elasticsearch elasticsearch-env elasticsearch-keystore elasticsearch-plugin elasticsearch-translog x-pack```
root@master /usr/share/elasticsearch :)
11:55 AM Tue Oct 10# java -version

i also tried @shreejay logic for java 8

could you point me where i am making mistake.
You have to set the ES_JAVA_OPTS variable to "-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005" and then starting Elasticsearch without any options or parameters.
Hi, needed to debug an elasticsearch plugin via IntelliJIDEA. (JDK 1.8, elasticsearch 5.4, Windows 10 x64)
I've managed to do it by adding -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005
inside \elasticsearch-5.4.0\config\jvm.options
file. I don't know why the "ES_JAVA_OPTS" method didn't work for me.
Thanks
@elbarto93 , setting ES_JAVA_OPTS did not work because the value is getting set by groovy script, hence it is getting over written.

i changed the port at this line and then from commandline ran ./gradlew run --debug-jvm, then the port was 5005 instead of 8000
Thanks

For step 2 - if using java 8, the options will be
