配置文档：https://www.cnblogs.com/mijino/p/14874765.html

执行全量同步 curl -X POST http://localhost:8081/etl/es7/student.yml 出现如下错误：

{"succeeded":false,"resultMessage":"导入ES 数据：2 条","errorMessage":"student etl failed! ==>全量数据 etl 异常 ElasticsearchException[Elasticsearch exception [type=cluster_block_exception, reason=index [student] blocked by: [TOO_MANY_REQUESTS/12/disk usage exceeded flood-stage watermark, index has read-only-allow-delete block];]]"}%

解决方法

PUT _cluster/settings
{
   "transient": {
       "cluster.routing.allocation.disk.watermark.low": "100gb",
       "cluster.routing.allocation.disk.watermark.high": "50gb",
       "cluster.routing.allocation.disk.watermark.flood_stage": "10gb",
       "cluster.info.update.interval": "1m"
   }
}

PUT /_cluster/settings
{
    "transient": {
        "cluster.routing.allocation.disk.threshold_enabled": false
    }
}
