logstash报错
[2019-07-07T21:21:46,183][INFO ][logstash.outputs.elasticsearch] retrying failed action with response code: 403 ({"type"=>"cluster_block_exception", "reason"=>"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"})
因为ES集群有一个磁盘满了
先删除磁盘
再执行
curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

1.7版本以上重新创建表
https://blog.csdn.net/hanglinux/article/details/75645756
{
"detail": "'staticfiles' is not a registered tag library. Must be one of:\nadmin_list\nadmin_modify\nadmin_static\nadmin_urls\ncache\nfuture\ni18n\nl10n\nlog\nrest_framework\nstatic\ntz"
}
不要用Response ，用 JsonReponse
{"detail": " is not JSON serializable"}
dict或list里包含了 Objcet 类型的数据
中文需要指定字符集
idc_node_list = [u'运维审批']
task_list = [u'运维审批', u'啊啊水电费']
idc_node = list(set(idc_node_list).intersection(set(task_list)))
