Move to elasticsearch with heatmap support

[JorgeMartinezG]

• Test heatmap works via api
• Test heatmap in OL3
• Fix tests

[ingenieroariel]

@JorgeMartinezG to fix tests you will first have to uncomment them. I believe @panchicore commented them all I but I am not sure why.

Travis tests won't pass because this version of elasticsearch has permission issues when the docker image is run on Linux environments. I tested in Ubuntu 16.04 with this ouput.

Checking in the forums....they recommend to grant permissions. Any thoughts? @ingenieroariel @sstults

Can you run the tests with the official 5.0.0 image [0] and then use that Dockerfile as the basis for this one? [1]

[0] https://github.com/docker-library/elasticsearch/blob/master/5.0/Dockerfile
[1] Switch to the following image: elasticsearch:5.0.0-rc1 from https://hub.docker.com/_/elasticsearch/

[JorgeMartinezG]

It's a good idea. However, that elasticsearch version won't have the gridlevel support, because the current dockerfile pulls from this repo:

https://github.com/sstults/elasticsearch/

[ingenieroariel]

Right - what I mean is building that elastic search exactly like the official one. Or using the official one and then just replacing the artifacts with ones compiled from the branch

[JorgeMartinezG]

Virtual memory map area in Linux, comes with a small value. This causes elasticsearch to stop execution on its container, making travis fail. Fix is already sent in PR with tests passed

#231

[JorgeMartinezG]

Heatmap test is failing executing one assertion. The test was created to assert if a returning value is None. However, in solr, the returned value is an empty list. For elasticsearch, is a list of empty lists.

ES_JAVA_OPTS="-Xms512m -Xmx512m" ./elasticsearch/bin Solves the problem for me

@JorgeMartinezG @ingenieroariel can this be closed?
