How to remove elasticsearch?

Question

I am trying to make logstash work with elasticsearch and Kibana. I had all the latest versions, but after I faced a few problems, I realized that I needed to install an older version, i.e., 0.20.6, of elasticsearch in order for it to work correctly with the latest version of logstash. So, I downloaded the older version, did an rm -rf of the older (v.0.90.x) one and installed the new (v.0.20.6) one. I tried to start it up. It starts, but then gives me repeating errors like:

As you can see, it is still trying to look for the v.0.90.x installation. My localhost:9200 shows the following output:

{
  "ok" : true,
  "status" : 200,
  "name" : "Blob",
  "version" : {
    "number" : "0.90.2",
    "snapshot_build" : false,
    "lucene_version" : "4.3.1"
  },
  "tagline" : "You Know, for Search"
}

How do I solve this to use v.0.20.6?

Answer 1

It looks like you still have 0.90 running. You need to shutdown it before you can switch to 0.20. The simplest way to do it is by running

curl -XPOST 10.1.10.52:9200/_shutdown

If this doesn't work, find the java process that elasticsearch is running in and kill it.

After 0.90 is down you might need to clean the directory again.
