Today I were try to deploy elasticsearch5 in my test server, and then update the default yml configure file about the cluster name to`es5` , but it's so strange after restart elasticsearch5 service. There still show up default cluster name is `elasticsearch`, but the log file name had rename to `es5.log`. So is there any wrong in my settings?
Note:
elasticsearch.yml
```auto
# ======================== 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:
#
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: es5
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: master01
#
# 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: /data/elastic
#
# Path to log files:
#
path.logs: /usr/local/elastic/elasticsearch-5.0.0-alpha5/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
# bootstrap.memory_lock: true
#
# Make sure that the heap size 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: 192.168.0.1
#
# Set a custom port for HTTP:
#
http.port: 9200
transport.tcp.port: 9300
transport.tcp.compress: true
```

Hi @elkan1788,
I just tried to do the same with Elasticsearch 5.0.0-alpha5 and it worked fine for me.
Just a couple of questions:
- Are you sure you hit the correct Elasticsearch instance?
- Did you restart Elasticsearch after you've changed the configuration file?

Sorry forgot reply you answer. There seem some lazy execute after change settings. The next time when I restart ES service it worked fine. Thanks.

Hi @elkan1788,
no worries, that happens. 🙂
You're right: You need to restart Elasticsearch after the change because you cannot change the name of a running cluster.
