Question

我在我的机器上运行了两个弹性搜索版本，一个是 1.7 ，其他 2.3 我可以在 1.7 版本中对文档编制索引，但同样的索引语句会在 2.3 中抛出u'caused_by': {u'reason': u'Java heap space', u'type': u'out_of_memory_error'}。

Elasticsearch 2.3

的映射

   {
    "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

的映射

  {
    "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doc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。它对我有用

从＆＃34; / etc / sysconfig＆＃34;

sudo vi / etc / sysconfig / elasticsearch

2.您可以在此处更改堆大小

ES_HEAP_SIZE =2克

（默认大小为2gb。您可以将其增加到可用ram的50％）
