简而言之,当在 Elasticsearch 查询中使用了无效的管道聚合时,会出现此错误。管道聚合用于对其他聚合的输出进行聚合。该错误表示 Elasticsearch 无法识别指定的管道聚合。要解决此问题,请确保使用的管道聚合有效且拼写正确。此外,请检查您使用的 Elasticsearch 版本是否支持您尝试使用的管道聚合。如果不支持,您可能需要升级 Elasticsearch 版本。
日志上下文 #
日志 “Invalid pipeline aggregation named [” 的类名是 AggregationPhase.java。我们从 Elasticsearch 源代码中提取了以下内容,供那些寻求深入上下文的人参考:
List<SiblingPipelineAggregator> siblingPipelineAggregators = new ArrayList<>(pipelineAggregators.size());
for (PipelineAggregator pipelineAggregator : pipelineAggregators) {
if (pipelineAggregator instanceof SiblingPipelineAggregator) {
siblingPipelineAggregators.add((SiblingPipelineAggregator) pipelineAggregator);
} else {
throw new AggregationExecutionException("Invalid pipeline aggregation named [" + pipelineAggregator.name()
+ "] of type [" + pipelineAggregator.getWriteableName() + "]. Only sibling pipeline aggregations are "
+ "allowed at the top level");
}
}
context.queryResult().aggregations(new InternalAggregations(aggregations, siblingPipelineAggregators));
