[overlord-issues] [JBoss JIRA] (RTGOV-574) Investigate 'index already exists' exception when previous command indicates does not exist

Investigate 'index already exists' exception when previous command indicates does not exist ------------------------------------------------------------------------------------------- Key: RTGOV-574 URL: https://issues.jboss.org/browse/RTGOV-574 Project: RTGov (Run Time Governance) Issue Type: Task Reporter: Gary Brown Assignee: Gary Brown Fix For: 2.0.0.Final When updating to Elasticsearch 1.3.2 (RTGOV-568), noticed that when the EAP server was restarted, it resulted in an IndexAlreadyExistsException from ES. However this exception was generated from code called to create the indexes - however prior to that call it checks with the ES node whether the indexes already exist. Ivan McKinley found the following reference that may be relevant: http://stackoverflow.com/questions/23883110/elasticsearch-index-exists-no... He also suggests: "If this is the problem then we may have an impact from running “embedded” mode. The more data we have the longer response from the async process perhaps. externalising the es process may resolve this.. and another test is to remove the entire contents of the index/type/ to further prove that we are affect the amount of data. The various scenarios here are definitely interesting for us regarding documentation"
