Elasticsearch 2.3 vs elasticsearch 1.7 Java Heap space

Question

我的机器上有两个elasticsearch版本，一个是1.7，另一个是2.3我能够在1.7版本中索引文档，但相同的索引语句在2.3中抛出u'caused_by': {u'reason': u'Java heap space', u'type': u'out_of_memory_error'}。

Elasticsearch 2.3

   {
    "id": {
        "type": "integer",
        "store": "yes",
        "index": "analyzed"
    },
    "field1": {
        "type": "integer",
        "store": "yes",
        "index": "no"
    },
    "field2": {
        "type": "integer",
        "store": "yes",
        "index": "no"
    },
    "field3": {
        "type": "string",
        "store": "yes",
        "index": "no"
    },
    "field4": {
        "type": "geo_shape",
        "tree": "legacyquadtree",
        "precision": "1mm"
    }
}

Elasticsearch 1.7

  {
    "id": {
        "type": "integer",
        "store": "yes",
        "index": "analyzed"
    },
    "field1": {
        "type": "integer",
        "store": "yes",
        "index": "no"
    },
    "field2": {
        "type": "integer",
        "store": "yes",
        "index": "no"
    },
    "field3": {
        "type": "string",
        "store": "yes",
        "index": "no"
    },
    "field4": {
        "type": "geo_shape",
        "tree": "quadtree",
        "precision": "1mm"
    }
}

用于索引的文档结构是(2.3和1.7相同)

      {
        "field4":
            {"type": "envelope", "coordinates":
                data},
        "id": id,
        "field1": val1,
        "field2": val2,
        "field3": val3
    }

指定的JAVA_HEAP_SIZE是两个版本的默认值

Answer 1

尝试增加JAVA_HEAP_SPACE。

1. 从"/etc/sysconfig"打开Elasticsearch文件

sudo vi/etc/sysconfig/elasticsearch

2。您可以在这里更改堆大小

ES_HEAP_SIZE = 2 g

(默认大小为2gb。您可以将其增加到可用内存的50%)
