最近几天的push:user:req数据写不到集群，报错如下：

搜索了下：
是lucene的文档数限制，每个分片最大支持2的31次方个文档数量
https://discuss.elastic.co/t/lucene-max-documents-limit/34761
Lucene max documents limit，Yep, there is a 2^31 limit per shard in Lucene.
查询当前es分片文档：
# curl 10.26.241.237:/_cat/shards?v

查询出来的2147483519和2的31次方2147483648接近，所以新增加的数据无法插入
临时的解决办法：先把kafka的磁盘加到数据多保留一段时间20天
原来的集群数据抽取到hbase中作为冷数据处理，再把kafka里面的数据导入数据到新的集群中
