I am unable to start hte elasticsearch after the installation due to the below error. I have tried multiple options as recommended in other topics like reinstalling, enusing right java\_home, giving full permissions, but it didn't help. Please share solution if you have implemented any specific changes to resolve this. it would be helpful for me
