Question

在Elasticsearch版本5.x中删除了DeleteByQueryPlugin，转而使用Delete By Query API。要迁移到新API，我必须替换2.3代码：

DeleteByQueryResponse response = new     DeleteByQueryRequestBuilder(client(), DeleteByQueryAction.INSTANCE)
                .setIndices(INDEX_LOCKS)
                .setQuery(rangeQuery(EXPIRES_AT).lte(expiresAt))
                .execute()
                .actionGet();

使用新的5.x DeleteByQueryAction代码：

BulkIndexByScrollResponse response = DeleteByQueryAction.INSTANCE.newRequestBuilder(client())
                .filter(rangeQuery(EXPIRES_AT).lte(expiresAt))
                .source(INDEX_LOCKS)
                .get();

如果我启动服务器并测试代码，这工作正常。但它不适用于我的集成测试。以下测试代码抛出异常：

Testcode：

public class DeleteByQueryTest extends ESIntegTestCase {

    private static final String INDEX_LOCKS = "locks";
    private static final String INDEX_ARTICLES = "articles";
    private static final String LOCK_TYPE = "lock";
    private static final String LOCK_ID = "something";

    @Before
    public void waitForIndex() {
        createIndex(INDEX_LOCKS, INDEX_ARTICLES);
        ensureGreen(INDEX_LOCKS, INDEX_ARTICLES);
    }

    @Test
    public void shouldDeleteByQuery() {
        IndexResponse indexResponse = client().prepareIndex(INDEX_LOCKS, LOCK_TYPE, LOCK_ID).setSource("{}").setCreate(true).get();
        assertThat(indexResponse.getId(), is(LOCK_ID));
        refresh();

        BulkIndexByScrollResponse response = DeleteByQueryAction.INSTANCE.newRequestBuilder(client())
            .filter(idsQuery(LOCK_TYPE).addIds(LOCK_ID))
            .source(INDEX_LOCKS)
            .get();

        assertThat(response.getDeleted(), is(1L));
    }
}

发生的异常：

有没有人遇到同样的问题，知道该怎么做？

解决方案是在测试代码中添加reindex插件：

@Override
protected Collection<Class<? extends Plugin>> nodePlugins() {
    return Collections.singleton(ReindexPlugin.class);
}

@Override
protected Collection<Class<? extends Plugin>> transportClientPlugins() {
    return Collections.singleton(ReindexPlugin.class);
}

将Elasticsearch的DeleteByQueryPlugin从2.4迁移到5.2.2
