Description

The symptom is that the jena-text-es build fails with this error:

[ERROR] Failed to execute goal com.github.alexcojocaru:elasticsearch-maven-plugin:5.2:runforked (start-elasticsearch) on project jena-text-es: Condition returned by method "waitToStart" in class com.github.alexcojocaru.mojo.elasticsearch.v2.client.Monitor was not fulfilled within 30 seconds. -> [Help 1]

The problem seems to be that Elasticsearch starts up slowly and the elasticsearch-maven-plugin times out at 30 seconds.

I found a way to trigger this by simulating high load using the stress utility:

$ stress --cpu 3 -i 3 -d 3
stress: info: [29489] dispatching hogs: 3 cpu, 3 io, 0 vm, 3 hdd

Increasing the ES startup timeout should help. I will prepare a PR shortly.
