Unable to install Elasticsearch on Mac Sierra (10.12.2)

When attempting to start Elasticsearch 5.1.1 via

$ elasticsearch

I get the output:

Error: Could not find or load main class -Xms2g

I've looked into:

  1. I read it may be an error in how a class is called? But I'm not exposed to doing that. This thread doesn't help and isn't really my problem as I'm not installing a plugin.

  2. I installed via Homebrew. Here is some output from that:

    $ brew info elasticsearch
elasticsearch: stable 5.1.1, HEAD

To have launchd start elasticsearch now and restart at login:
  brew services start elasticsearch
Or, if you don't want/need a background service you can just run:
  elasticsearch

$ brew doctor
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
  mongodb
  ruby

  3. I also tried originally installing via manually extracting the .tar.gz package. I at first got some Java permission denied errors, but after running a chown to admin for myself I also got this same Error: Could not find or load main class type error.

  4. I just updated my Java JDK to the latest: 1.8.0_112 and set my JAVA_HOME variable to that directory accordingly.

  5. The most recent version of Elasticsearch 2 (2.4.3) works. Meanwhile, Elasticsearch v5.0.2 fails.

What can I do to have Elasticsearch properly installed on my Mac?

Solution

  • You most likely have a problem in your .bash_profile. Usually elastic starts out of the box on a mac.
