总是查询不成功,求讲解
es日志的信息是:[2016-10-17 19:23:48,029][WARN ][transport.netty          ] [node-1] exception caught on transport layer [[id: 0x1fce887e, /10.20.20.13:65479 => /10.20.20.13:9300]], closing connection

es配置文件的信息,# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please see the documentation for further information on configuration options:
# <http://www.elastic.co/guide/en ... gt%3B
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
  cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
  node.name: node-1
#
# Add custom attributes to the node:
#
  node.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
# path.data: /path/to/data
#
# Path to log files:
#
# path.logs: /path/to/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
# bootstrap.mlockall: true
#
# Make sure that the `ES_HEAP_SIZE` environment variable is set to about half the memory
# available on the system and that the owner of the process is allowed to use this limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
  network.host: 10.20.20.13
#
# Set a custom port for HTTP:
#
  http.port: 9200
  
  transport.tcp.port: 9300
  
  transport.tcp.compress: true
  
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en ... gt%3B
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
# discovery.zen.ping.unicast.hosts: ["host1", "host2"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of nodes / 2 + 1):
#
# discovery.zen.minimum_master_nodes: 3
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en ... gt%3B
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
# gateway.recover_after_nodes: 3
#
# For more information, see the documentation at:
# <http://www.elastic.co/guide/en ... gt%3B
#
# ---------------------------------- Various -----------------------------------
#
# Disable starting multiple nodes on a single system:
#
# node.max_local_storage_nodes: 1
#
# Require explicit names when deleting indices:
#
# action.destructive_requires_name: true

13ip 稳定么,如果有多个节点,可以设置 sniff 参数来感知其他节点,

Settings settings = Settings.settingsBuilder() .put("client.transport.sniff", true).build();
