Hi,
I read with interest the news about the Azure Cloud Plugin over the
weekend and today have been trying to get it working with Windows VMs on
Azure with mixed levels of success.
I have two environments/clusters one which has been running for a few weeks
and another which is brand new and only been running for a couple of days;
both have the head plugin installed so I can see the status of the
cluster(s).
All of the clusters consist of 3 machines are using the Windows Server 2012
R2 Datacenter base image with java 7 added, and elasticsearch 0.90.10
installed as a service set to automatic startup.
Cluster 1 - been running using multicast discovery disabled and the ip
addresses of the nodes listed. I have since installed the azure cloud
plugin, added the certificate and configuration to the node and enabled
multicast discovery again and commented out the list of ip addresses. Now
when I view the details of the cluster, none of the nodes can see each
other and the cluster health status is marked in amber as the full cluster
is no longer available.
the elasticsearch.yml file is as follows:
##################### ElasticSearch Configuration Example
#####################
# This file contains an overview of various configuration settings,
# targeted at operations staff. Application developers should
# consult the guide at <http://elasticsearch.org/guide>.
#
# The installation procedure is covered at
# <
http://elasticsearch.org/guide/en/elasticsearch/reference/current/setup.html
>.
#
# ElasticSearch comes with reasonable defaults for most settings,
# so you can try it out without bothering with configuration.
#
# Most of the time, these defaults are just fine for running a production
# cluster. If you're fine-tuning your cluster, or wondering about the
# effect of certain configuration option, please _do ask_ on the
# mailing list or IRC channel [http://elasticsearch.org/community].
# Any element in the configuration can be replaced with environment
variables
# by placing them in ${...} notation. For example:
#
# node.rack: ${RACK_ENV_VAR}
# For information on supported formats and syntax for the config file, see
# <
http://elasticsearch.org/guide/en/elasticsearch/reference/current/setup-configuration.html
>
################################### Cluster
###################################
# Cluster name identifies your cluster for auto-discovery. If you're running
# multiple clusters on the same network, make sure you're using unique
names.
#
cluster.name: elasticsearch
#################################### Node
#####################################
# Node names are generated dynamically on startup, so you're relieved
# from configuring them manually. You can tie this node to a specific name:
#
# node.name: "Franz Kafka"
# Every node can be configured to allow or deny being eligible as the
master,
# and to allow or deny to store the data.
#
# Allow this node to be eligible as a master node (enabled by default):
#
# node.master: true
#
# Allow this node to store data (enabled by default):
#
# node.data: true
# You can exploit these settings to design advanced cluster topologies.
#
# 1. You want this node to never become a master node, only to hold data.
# This will be the "workhorse" of your cluster.
#
# node.master: false
# node.data: true
#
# 2. You want this node to only serve as a master: to not store any data and
# to have free resources. This will be the "coordinator" of your cluster.
#
# node.master: true
# node.data: false
#
# 3. You want this node to be neither master nor data node, but
# to act as a "search load balancer" (fetching data from nodes,
# aggregating results, etc.)
#
# node.master: false
# node.data: false
# Use the Cluster Health API [http://localhost:9200/_cluster/health], the
# Node Info API [http://localhost:9200/_cluster/nodes] or GUI tools
# such as <http://github.com/lukas-vlcek/bigdesk> and
# <http://mobz.github.com/elasticsearch-head> to inspect the cluster state.
# A node can have generic attributes associated with it, which can later be
used
# for customized shard allocation filtering, or allocation awareness. An
attribute
# is a simple key value pair, similar to node.key: value, here is an
example:
#
# node.rack: rack314
# By default, multiple nodes are allowed to start from the same
installation location
# to disable it, set the following:
# node.max_local_storage_nodes: 1
#################################### Index
####################################
# You can set a number of options (such as shard/replica options, mapping
# or analyzer definitions, translog settings, ...) for indices globally,
# in this file.
#
# Note, that it makes more sense to configure index settings specifically
for
# a certain index, either when creating it or by using the index templates
API.
#
# See <
http://elasticsearch.org/guide/en/elasticsearch/reference/current/index-modules.html>
and
# <
http://elasticsearch.org/guide/en/elasticsearch/reference/current/indices-create-index.html
>
# for more information.
# Set the number of shards (splits) of an index (5 by default):
#
# index.number_of_shards: 5
# Set the number of replicas (additional copies) of an index (1 by default):
#
# index.number_of_replicas: 1
# Note, that for development on a local machine, with small indices, it
usually
# makes sense to "disable" the distributed features:
#
# index.number_of_shards: 1
# index.number_of_replicas: 0
# These settings directly affect the performance of index and search
operations
# in your cluster. Assuming you have enough machines to hold shards and
# replicas, the rule of thumb is:
#
# 1. Having more *shards* enhances the _indexing_ performance and allows to
# _distribute_ a big index across machines.
# 2. Having more *replicas* enhances the _search_ performance and improves
the
# cluster _availability_.
#
# The "number_of_shards" is a one-time setting for an index.
#
# The "number_of_replicas" can be increased or decreased anytime,
# by using the Index Update Settings API.
#
# ElasticSearch takes care about load balancing, relocating, gathering the
# results from nodes, etc. Experiment with different settings to fine-tune
# your setup.
# Use the Index Status API (<http://localhost:9200/A/_status>) to inspect
# the index status.
#################################### Paths
####################################
# Path to directory containing configuration (this file and logging.yml):
#
# path.conf: /path/to/conf
# Path to directory where to store index data allocated for this node.
#
# path.data: /path/to/data
#
# Can optionally include more than one location, causing data to be striped
across
# the locations (a la RAID 0) on a file level, favouring locations with
most free
# space on creation. For example:
#
# path.data: /path/to/data1,/path/to/data2
# Path to temporary files:
#
# path.work: /path/to/work
# Path to log files:
#
# path.logs: /path/to/logs
# Path to where plugins are installed:
#
# path.plugins: /path/to/plugins
#################################### Plugin
###################################
# If a plugin listed here is not installed for current node, the node will
not start.
#
# plugin.mandatory: mapper-attachments,lang-groovy
################################### Memory
####################################
# ElasticSearch performs poorly when JVM starts swapping: you should ensure
that
# it _never_ swaps.
#
# Set this property to true to lock the memory:
#
# bootstrap.mlockall: true
# Make sure that the ES_MIN_MEM and ES_MAX_MEM environment variables are set
# to the same value, and that the machine has enough memory to allocate
# for ElasticSearch, leaving enough memory for the operating system itself.
#
# You should also make sure that the ElasticSearch process is allowed to
lock
# the memory, eg. by using `ulimit -l unlimited`.
############################## Network And HTTP
###############################
# ElasticSearch, by default, binds itself to the 0.0.0.0 address, and
listens
# on port [9200-9300] for HTTP traffic and on port [9300-9400] for
node-to-node
# communication. (the range means that if the port is busy, it will
automatically
# try the next port).
# Set the bind address specifically (IPv4 or IPv6):
#
# network.bind_host: 192.168.0.1
# Set the address other nodes will use to communicate with this node. If not
# set, it is automatically derived. It must point to an actual IP address.
#
# network.publish_host: 192.168.0.1
# Set both 'bind_host' and 'publish_host':
#
# network.host: 192.168.0.1
# Set a custom port for the node to node communication (9300 by default):
#
# transport.tcp.port: 9300
# Enable compression for all communication between nodes (disabled by
default):
#
# transport.tcp.compress: true
# Set a custom port to listen for HTTP traffic:
#
# http.port: 9200
# Set a custom allowed content length:
#
# http.max_content_length: 100mb
# Disable HTTP completely:
#
# http.enabled: false
################################### Gateway
###################################
# The gateway allows for persisting the cluster state between full cluster
# restarts. Every change to the state (such as adding an index) will be
stored
# in the gateway, and when the cluster starts up for the first time,
# it will read its state from the gateway.
# There are several types of gateway implementations. For more information,
see
# <
http://elasticsearch.org/guide/en/elasticsearch/reference/current/modules-gateway.html
>.
# The default gateway type is the "local" gateway (recommended):
#
# gateway.type: local
# Settings below control how and when to start the initial recovery process
on
# a full cluster restart (to reuse as much local data as possible when
using shared
# gateway).
# Allow recovery process after N nodes in a cluster are up:
#
# gateway.recover_after_nodes: 1
# Set the timeout to initiate the recovery process, once the N nodes
# from previous setting are up (accepts time value):
#
# gateway.recover_after_time: 5m
# Set how many nodes are expected in this cluster. Once these N nodes
# are up (and recover_after_nodes is met), begin recovery process
immediately
# (without waiting for recover_after_time to expire):
#
# gateway.expected_nodes: 2
############################# Recovery Throttling
#############################
# These settings allow to control the process of shards allocation between
# nodes during initial recovery, replica allocation, rebalancing,
# or when adding and removing nodes.
# Set the number of concurrent recoveries happening on a node:
#
# 1. During the initial recovery
#
# cluster.routing.allocation.node_initial_primaries_recoveries: 4
#
# 2. During adding/removing nodes, rebalancing, etc
#
# cluster.routing.allocation.node_concurrent_recoveries: 2
# Set to throttle throughput when recovering (eg. 100mb, by default 20mb):
#
# indices.recovery.max_bytes_per_sec: 20mb
# Set to limit the number of open concurrent streams when
# recovering a shard from a peer:
#
# indices.recovery.concurrent_streams: 5
################################## Discovery
##################################
# Discovery infrastructure ensures nodes can be found within a cluster
# and master node is elected. Multicast discovery is the default.
# Set to ensure a node sees N other master eligible nodes to be considered
# operational within the cluster. Its recommended to set it to a higher
value
# than 1 when running more than 2 nodes in the cluster.
#
# discovery.zen.minimum_master_nodes: 1
# Set the time to wait for ping responses from other nodes when discovering.
# Set this option to a higher value on a slow or congested network
# to minimize discovery failures:
#
# discovery.zen.ping.timeout: 3s
# For more information, see
# <
http://elasticsearch.org/guide/en/elasticsearch/reference/current/modules-discovery-zen.html
>
# Unicast discovery allows to explicitly control which nodes will be used
# to discover the cluster. It can be used when multicast is not present,
# or to restrict the cluster communication-wise.
#
# 1. Disable multicast discovery (enabled by default):
#
# discovery.zen.ping.multicast.enabled: false
#
# 2. Configure an initial list of master nodes in the cluster
# to perform discovery when new nodes (master or data) are started:
#
# discovery.zen.ping.unicast.hosts: ["10.0.0.4", "10.0.0.5", "10.0.0.6"]
# EC2 discovery allows to use AWS EC2 API in order to perform discovery.
#
# You have to install the cloud-aws plugin for enabling the EC2 discovery.
#
# For more information, see
# <
http://elasticsearch.org/guide/en/elasticsearch/reference/current/modules-discovery-ec2.html
>
#
# See <http://elasticsearch.org/tutorials/elasticsearch-on-ec2/>
# for a step-by-step tutorial.

Cluster 2 - brand new clean cluster with same base configuration and only
differences in elasticsearch.yml file are subscription id, service name and
cluster name. Once again none of the nodes in this configuration can see
each other.
I suspect this is a configuration issue but my experience with
elasticsearch is limited. Does anyone have any ideas what I could have
configured incorrectly?
Thanks
