解决方法
保持代码中集群名与elaticsearch.yml的配置一致
代码中集群名为默认的elasticsearch。
Settings settings = Settings.settingsBuilder().put(
"cluster.name",
"elasticsearch").put(
"client.transport.sniff",
true).build();
elaticsearch.yml
cluster.name: elasticsearch
改系统配置
1.vim /etc/sysctl.conf
2.在末尾添加：
net.ipv4.tcp_keepalive_time=
600
net.ipv4.tcp_keepalive_intvl=
60
net.ipv4.tcp_keepalive_probes=
3
3.sysctl -p时期立即生效
到此为止，重启es即可。暂时记录修改方法，日后会更新博客写明原因。
