Hi there! I have a small cluster that was running fine on Elastic 1.4.2 and due to the stability improvements mentioned on 1.5 we decided to upgrade. The upgrade was done as a rolling upgrade (one instance at a time) and everything appeared to be going fine.
We don't use Logstash, but we do split our indexes by day. Once the day changed and a new index was automatically created we started getting a lot of these messages: [2015-05-11 13:35:49,852][DEBUG][action.search.type ] [elastic01] [ events_2015-03-17][2], node[8GzJ8I3YSAChFxmK9a4drQ], [R], s[STARTED]: Failed to execute [org.elasticsearch.action.search.SearchRequest@51be6ea0] lastShard [true] org.elasticsearch.transport.RemoteTransportException: [elastic03][inet[/ 192.168.171.33:9300]][indices:data/read/search[phase/query]] Caused by: java.lang.ClassCastException [2015-05-11 13:35:49,853][DEBUG][action.search.type ] [elastic01] [ events_2015-03-17][0], node[8GzJ8I3YSAChFxmK9a4drQ], [P], s[STARTED]: Failed to execute [org.elasticsearch.action.search.SearchRequest@51be6ea0] lastShard [true] org.elasticsearch.transport.RemoteTransportException: [elastic03][inet[/ 192.168.171.33:9300]][indices:data/read/search[phase/query]] Caused by: java.lang.ClassCastException We didn't modify our code at all, just upgraded the version of Elasticsearch running on the cluster. Is this message harmless? What can I do to fix it or help you guys debug this? Thanks in advance, Eduardo Castegnaro. -- Please update your bookmarks!
