How to remove elasticsearch?
elasticsearch
Solution
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.
Problem
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: ``` [2013-07-29 14:24:04,718][WARN ][indices.cluster ] [Dansen Macabre] [blog][2] failed to start shard org.elasticsearch.indices.recovery.RecoveryFailedException: [blog][2]: Recovery failed from [Blob][UCFJzrBxQHOYOohF6scQMw][inet[/10.1.10.52:9300]] into [Dansen Macabre][-GzBNHLJSc2Do5DNTsn1jw][inet[/10.1.10.52:9301]] at org.elasticsearch.indices.recovery.RecoveryTarget.doRecovery(RecoveryTarget.java:293) at org.elasticsearch.indices.recovery.RecoveryTarget.access$300(RecoveryTarget.java:62) at org.elasticsearch.indices.recovery.RecoveryTarget$2.run(RecoveryTarget.java:163) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:724) Caused by: org.elasticsearch.transport.RemoteTransportException: [Blob][inet[/10.1.10.52:9300]][index/shard/recovery/startRecovery] Caused by: org.elasticsearch.index.engine.RecoveryEngineException: [blog][2] Phase[1] Execution failed at org.elasticsearch.index.engine.robin.RobinEngine.recover(RobinEngine.java:1123) at org.elasticsearch.index.shard.service.InternalIndexShard.recover(InternalIndexShard.java:526) at org.elasticsearch.indices.recovery.RecoverySource.recover(RecoverySource.java:116) at org.elasticsearch.indices.recovery.RecoverySource.access$1600(RecoverySource.java:60) at org.elasticsearch.indices.recovery.RecoverySource$StartRecoveryTransportRequestHandler.messageReceived(RecoverySource.java:328) at org.elasticsearch.indices.recovery.RecoverySource$StartRecoveryTransportRequestHandler.messageReceived(RecoverySource.java:314) at org.elasticsearch.transport.netty.MessageChannelHandler$RequestHandler.run(MessageChannelHandler.java:265) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:724) Caused by: org.elasticsearch.indices.recovery.RecoverFilesRecoveryException: [blog][2] Failed to transfer [25] files with total size of [3.7kb] at org.elasticsearch.indices.recovery.RecoverySource$1.phase1(RecoverySource.java:226) at org.elasticsearch.index.engine.robin.RobinEngine.recover(RobinEngine.java:1116) ... 9 more Caused by: java.io.FileNotFoundException: /Users/CiC/BigData/elasticsearch-0.90.2/data/elasticsearch/nodes/0/indices/blog/2/index/_1_es090_0.doc (No such file or directory) at java.io.RandomAccessFile.open(Native Method) at java.io.RandomAccessFile.<init>(RandomAccessFile.java:233) at org.apache.lucene.store.FSDirectory$FSIndexInput.<init>(FSDirectory.java:410) at org.apache.lucene.store.NIOFSDirectory$NIOFSIndexInput.<init>(NIOFSDirectory.java:123) at org.apache.lucene.store.NIOFSDirectory.openInput(NIOFSDirectory.java:80) at org.apache.lucene.store.RateLimitedFSDirectory.openInput(RateLimitedFSDirectory.java:99) at org.elasticsearch.index.store.Store.openInputRaw(Store.java:271) at org.elasticsearch.indices.recovery.RecoverySource$1$1.run(RecoverySource.java:171) ... 3 more ``` 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?
