我们正在丢失弹性搜索集群中的数据

我们与ElasticSearch合作,但在这样做时,我们在群集环境中丢失了数据。我们使用ES 2.4.0。

有谁可以说我们缺少什么?

我们的情景是:

  1. 使用以下配置打开Elastic Server-1和Server-2, 他们在一个集群中。

  2. Server-1上的索引文档:

    curl -XPUT' 20.20.20.5:9200 / ert / post / 1' -d' { "用户":" easlan", " postDate":" 01-16-2015", " body":"在ElasticSearch Cluster中添加数据" , " title":" ElasticSearch Cluster Test - 1" }'

  3. 查找Server-1或Server-2上的索引文档:结果总数为1(按预期方式):

    curl -XGET' 20.20.20.5:9200 / ert / post / _search?q = user:easlan& pretty = true' curl -XGET' 20.20.20.6:9200 / ert / post / _search?q = user:easlan& pretty = true'

  4. 然后关闭Server-1

  5. 通过Server-2索引新文档:

    curl -XPUT' 20.20.20.6:9200 / ert / post / 2' -d' { "用户":" easlan", " postDate":" 01-16-2015", " body":"在ElasticSearch Cluster中添加数据" , " title":" ElasticSearch Cluster Test - 2"  }'

  6. 查找Server-2上的索引文档:结果总数为2:

    curl -XGET' 20.20.20.6:9200 / ert / post / _search?q = user:easlan& pretty = true'

  7. 关闭Server-2

  8. Open Server-1

  9. 查找Server-1上的索引文档:结果总数为1(正如预期的那样,因为server-2已关闭):

    curl -XGET' 20.20.20.5:9200 / ert / post / _search?q = user:easlan& pretty = true'

  10. 然后再次打开Server-2。在Server-1或Server-2上查找索引文档。我们希望看到结果总数为2,但是当我们看时,结果得到1。即使我们再次重启其中两个,结果仍然是1:

    curl -XGET' 20.20.20.5:9200 / ert / post / _search?q = user:easlan& pretty = true' curl -XGET' 20.20.20.6:9200 / ert / post / _search?q = user:easlan& pretty = true'

  11. 我们的配置:

    *** Server-1 ****
    cluster.name: ESCluster
    node.master: true
    node.name: "es1"
    node.data: true
    network.bind_host: ["127.0.0.1","20.20.20.5"]
    network.publish_host: "20.20.20.5"
    discovery.zen.ping.multicast.enabled: false
    discovery.zen.ping.unicast.hosts: ["20.20.20.5","20.20.20.6"]
    discovery.zen.minimum_master_nodes: 1
    
    *** Server-2 ****
    cluster.name: ESCluster
    node.master: true
    node.name: "es2"
    node.data: true
    network.bind_host: ["127.0.0.1","20.20.20.6"]
    network.publish_host: "20.20.20.6"
    discovery.zen.ping.multicast.enabled: false
    discovery.zen.ping.unicast.hosts: ["20.20.20.5","20.20.20.6"]
    discovery.zen.minimum_master_nodes: 1
