ElasticSearch and Java environment variable
STEP 1
Can you verify JAVA_HOME
is set to C:\Progra~1\Java\jdk1.8.0_20
,
C:\>echo %JAVA_HOME%
Also, verify java
command is available,
java -version
Reference
Check if JAVA_HOME is present in environment using batch script
STEP 2
If JAVA_HOME
is not set, please follow the steps provided here - How to Set Java Home in windows
Summary ,
- Right-click the My Computer icon on your desktop and select Properties.
- Click the Advanced tab. Click the Environment Variables button. Under System Variables, click New.
- Enter the variable name as JAVA_HOME.
Enter the variable value as the installation path for the JDK.
(eg.
C:\Progra~1\Java\jdk1.8.0_20
).- Click OK.
- Click Apply Changes.
run the below command:
set JAVA_HOME=C:\Program Files\Java\jre8
If elasticsearch version is 7.5 or higher, you find elasticsearch-7.X.Y\bin directory and then edit the elasticsearch-env.bat as the following:
if defined JAVA_HOME (
set JAVA="%WRITE_ELASTICSEARCH_JAVA_PATH%\bin\java.exe" //write java custom path. Edit only this line
set JAVA_TYPE=JAVA_HOME
) else (
set JAVA="%ES_HOME%\jdk\bin\java.exe"
set JAVA_HOME="%ES_HOME%\jdk"
set JAVA_TYPE=bundled jdk
)
You can customize the java path like that for elasticsearch.
A workaround if you do not have privileges to set up the environmental variables:
open the elasticsearch.bat file,
a) Remove the line:
if NOT DEFINED JAVA_HOME goto err
b) Replace %JAVA_HOME% with your java jdk path, something like: C:\Program Files\Java\jdk1.7.0_51
And for your terminal getting started and you not being able to type anything, it is the elasticsearch server, you need to connect to it using a client like cygwin.

For connecting to the server refer the elasticsearch documentation.
