Today we upgraded the cluster to recent Elasticsearch 1.4 branch, after upgrade we are seeing this message in the master logs. [2015-04-28 14:40:47,942][ERROR][marvel.agent] [els-master] Exporter [es\_exporter] has thrown an exception: java.lang.NullPointerException at org.elasticsearch.index.cache.query.QueryCacheStats.add(QueryCacheStats.java:52) at org.elasticsearch.action.admin.indices.stats.CommonStats.add(CommonStats.java:389) at org.elasticsearch.action.admin.indices.stats.IndicesStatsResponse.getTotal(IndicesStatsResponse.java:117) at org.elasticsearch.marvel.agent.exporter.ESExporter.exportIndicesStats(ESExporter.java:198) at org.elasticsearch.marvel.agent.AgentService$ExportingWorker.exportIndicesStats(AgentService.java:301) at org.elasticsearch.marvel.agent.AgentService$ExportingWorker.run(AgentService.java:260) at java.lang.Thread.run(Thread.java:745) I tried to install the latest version of marvel, but still the same issue. I wonder if someone else is facing it or we have something special going on in our setup. - Gurvinder -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

It truns out the problem was caused by mix of nodes during our rolling upgrade. So when cluster with nodes from 1.3.6 & 1.4.5 will face the problem I mentioned below. Once all nodes are upgraded to 1.4.5, marvel issue went away. Useful to know while upgrade 🙂 - Gurvinder On 04/28/2015 02:48 PM, Gurvinder Singh wrote: > Today we upgraded the cluster to recent Elasticsearch 1.4 branch, after > upgrade we are seeing this message in the master logs. > > [2015-04-28 14:40:47,942][ERROR][marvel.agent] [els-master] > Exporter [es\_exporter] has thrown an exception: > java.lang.NullPointerException > at > org.elasticsearch.index.cache.query.QueryCacheStats.add(QueryCacheStats.java:52) > at > org.elasticsearch.action.admin.indices.stats.CommonStats.add(CommonStats.java:389) > at > org.elasticsearch.action.admin.indices.stats.IndicesStatsResponse.getTotal(IndicesStatsResponse.java:117) > at > org.elasticsearch.marvel.agent.exporter.ESExporter.exportIndicesStats(ESExporter.java:198) > at > org.elasticsearch.marvel.agent.AgentService$ExportingWorker.exportIndicesStats(AgentService.java:301) > at > org.elasticsearch.marvel.agent.AgentService$ExportingWorker.run(AgentService.java:260) > at java.lang.Thread.run(Thread.java:745) > > I tried to install the latest version of marvel, but still the same > issue.
