It's installed as a linux service. It comes up and works fine using the bundled jdk(16).

```auto
[tsadmin@tsmkmslin04 ~]$ curl -XGET 'http://localhost:9200'
{
  "name" : "tsmkmslin04",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "MKY32C_DQxmTyU8Xfh7U9A",
  "version" : {
    "number" : "7.13.2",
    "build_flavor" : "default",
    "build_type" : "rpm",
    "build_hash" : "4d960a0733be83dd2543ca018aa4ddc42e956800",
    "build_date" : "2021-06-10T21:01:55.251515791Z",
    "build_snapshot" : false,
    "lucene_version" : "8.8.2",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

```

I change the ES\_JAVA\_HOME to any other jdk including jdk-16 or jdk-11 by editing /etc/sysconfig/elasticsearch file. Then it fails to come with below error :-

```auto
-- Unit elasticsearch.service has begun starting up.
Jul 02 15:54:46 tsmkmslin04 systemd-entrypoint[105988]: could not find java in ES_JAVA_HOME at /home/tsadmin/rajnish_openjdk11/jdk-16.0.1/bin/java
Jul 02 15:54:46 tsmkmslin04 systemd[1]: elasticsearch.service: Main process exited, code=exited, status=1/FAILURE

Jul 02 15:54:46 tsmkmslin04 systemd[1]: Failed to start Elasticsearch.

```

I have tried this with jdk-11 and with jdk-16. It's a valid path.

```auto
[tsadmin@tsmkmslin04 elasticsearch]$ /home/tsadmin/rajnish_openjdk11/jdk-16.0.1/bin/java -version
openjdk version "16.0.1" 2021-04-20
OpenJDK Runtime Environment (build 16.0.1+9-24)
OpenJDK 64-Bit Server VM (build 16.0.1+9-24, mixed mode, sharing)
[tsadmin@tsmkmslin04 elasticsearch]$ 

```

I am not able to figure out at all what's going wrong. Any help us appreciated.

1. have you tried pointing it at the home directory not the bin directory?

`/home/tsadmin/rajnish_openjdk11/jdk-16.0.1`

1. Also when you start elasticsearch as a service it starts as the `elasticsearch` user so it would need access / permissions to that path as well

1. This is how the changes look.  
ES\_JAVA\_HOME=/home/tsadmin/rajnish\_openjdk11/jdk-16.0.1  
From here elasticsearch automatically looks up for java in ES\_JAVA\_HOME/bin directory.

2. This is how the permission on jdk looks like  
You correctly pointed out. This was the reason. Thanks.
