You can try to IndicesExistsRequest and IndicesExistsResponse to verify that. You can build the request using IndicesAdminClient. I had ever used it and it worked for me. > -----Original Message----- > From: [elasticsearch@googlegroups.com](mailto:elasticsearch@googlegroups.com) > [[mailto:elasticsearch@googlegroups.com](mailto:elasticsearch@googlegroups.com)] On Behalf Of sam > Sent: 2011年8月26日 14:43 > To: elasticsearch > Subject: how to get index is exist in elastic cluster? > > Hi > > I Have situation where i want to delete index from cluster.before i need > to > check the availability of index in elastic server.if it available then go > for delete > an index.please tell me how to get the index exist in cluster using > elastic java > library. > > Thanks ---

You can also delete the index and only catch the IndexMissingException.

Just pay attention that it is a remote exception. > -----Original Message----- > From: [elasticsearch@googlegroups.com](mailto:elasticsearch@googlegroups.com) > [[mailto:elasticsearch@googlegroups.com](mailto:elasticsearch@googlegroups.com)] On Behalf Of David Pilato > Sent: 2011年8月26日 15:05 > To: [elasticsearch@googlegroups.com](mailto:elasticsearch@googlegroups.com) > Subject: Re: how to get index is exist in elastic cluster? > > You can also delete the index and only catch the IndexMissingException. > > David 😉 > > Le 26 août 2011 à 08:42, sam [mishra.sameek@gmail.com](mailto:mishra.sameek@gmail.com) a écrit : > > > Hi > > > > I Have situation where i want to delete index from cluster.before i > > need to check the availability of index in elastic server.if it > > available then go for delete an index.please tell me how to get the > > index exist in cluster using elastic java library. > > > > Thanks ---

I'm sorry I have to disagree. Here is what I wrote to force delete an index. ``` try { node.client().admin().indices() .delete(new DeleteIndexRequest("myindexname")).actionGet(); } catch (IndexMissingException e) { // Index does not exist... Fine } ``` As you can see, I catch the IndexMissingException which grand grand grand parent is a RuntimeException.

You might get it wrapped in a RemoteException as well, if it ended up coming from another node. The remove exception thingy is very handy when it comes to debugging (has a trace of all the nodes that the failure came from), but, it does not work amazingly well with java catch clauses... .
