Our spring boot app is indexing data in ES cluster using transport client [using ElasticsearchRepository ]. Issue is that after some index call indexing just hangs the.the SAVE method on DAO just hangs and After some time it gives us "Nonodefoundexception"
Here’s our stack
- ES 1.7.3
- Spring Boot: 1.3.2.RELEASE
- Java: 1.8
- spring-boot-starter-data-elasticsearch : 1.3.2.RELEASE
Using transport client:
ES setup: - there are three nodes. all are client and master and data
Environment: Our dev is in AWS and we do not see any issue in Dev even though all ES setup is same.
**org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes were available: [[NodeName-apsrp5470][TzlZ3u8aTK23YFr14R085g][apsrp5470][inet[/10.222.146.127:9300]]{master=true}, [NodeName-apsrp5434][K4r0wujuThqwj1oTU9lEHg][apsrp5434][inet[/10.222.146.132:9300]]{master=true}, [NodeName-apsrp5435][YBPk8E4TR6u7LFLxfaVWaw][apsrp5435][inet[/10.222.146.139:9300]]{master=true}]

I have experienced this error too. Here are the few cases where NoNodeException Occurs:
1) When we use HTTP port 9200 instead of 9300 on the JAVA client API in transport client.
2) When Elasticsearch jar and Java Client Jar version are mismatched.
3) Different Java version on Elasticsearch node and Client server.
4) When garbage collection is triggered , there would be a span of stop the world time. In this span the Java process will freeze and the node would give the same No node exception.
Reference
Please check these points.
回答2:
The 1.3.2.RELEASE version of the spring-boot-starter-data-elasticsearch only works with Elasticsearch 1.5.2.
You have two solutions:
- You downgrade your ES to 1.5.2 (instead of 1.7.3)
- You use version 1.4.0.BUILD-SNAPSHOT of
spring-boot-starter-data-elasticsearchwhich is based on ES 1.7.3
回答3:
Option is to try using another library if ES cannot be downgraded.
