Update Elasticsearch on logstash* to elasticsearch-1.7.0.deb
Closed, ResolvedPublic


1.6.1 or 1.7.0 fixes two security issues:

In addition OpenJDK fixes for the latest vulnerabilities in Java will probably be available by beginning of next week, so we can combine those two updates for the cluster restart.

Done. The addition of /_flush/synced in Elasticsearch 1.6.0 made this process much nicer than previous upgrades. The upgrade to 1.6.0 took a bit over 9 hours; the upgrade to 1.7.0 took less than 30 minutes.

#!/usr/bin/env bash

# Stop cluster from reallocating shards
curl -s -XPUT localhost:9200/_cluster/settings?pretty -d '{
  "transient" : {
    "cluster.routing.allocation.enable": "primaries"

# Set sync marker on idle shards
curl -s -XPOST 'localhost:9200/_flush/synced'

# Install new ES package
sudo service elasticsearch stop
sudo dpkg -i --force-confdef --force-confold /home/bd808/elasticsearch-1.7.0.deb
sudo service elasticsearch start

# Wait for service to restart
until curl -s localhost:9200/_cluster/health?pretty; do
    sleep 1

# Re-enable shard allocation
curl -s -XPUT localhost:9200/_cluster/settings?pretty -d '{
  "transient" : {
    "cluster.routing.allocation.enable": "all"

# Wait for the cluster to recover
until curl -s localhost:9200/_cluster/health?pretty |
    tee /tmp/health |
    grep green; do
    cat /tmp/health
    sleep 1

@Manybubbles said after that the curl -s -XPOST 'localhost:9200/_flush/synced' step shouldn't be necessary as Elasticsearch does this internally on idle shards.
