It works very well, thx!

Hello!

Maybe you can just wait for yellow or green status ? If you can just
execute a code like:

client.admin().cluster().health(new
ClusterHealthRequest().waitForGreenStatus()).actionGet();

I have figured out I can do this gets and searches operations using only
one node created in Java (I use default data node)
but I have to wait after gateway recovery process will end AND until
probably shards will be located in my one node.

So if I will run my Jave client like this:

Node node = nodeBuilder().node();
Client client = node.client();

    GetResponse response = client.prepareGet("twitter", "tweet", "2") 
      .execute()
      .actionGet();

I will get this exception ...

And for example if I will run Java client with more time to Gateway
recover and alocate shards like this:

Node node = nodeBuilder().node();
Client client = node.client();

    Thread.sleep(2000);
    
    GetResponse response = client.prepareGet("twitter", "tweet", "2") 
      .execute()
      .actionGet();

.
.
.

lut 03, 2013 6:38:41 PM org.elasticsearch.gateway
INFO: [Time Bomb] recovered [20] indices into cluster_state

I wont get any exception and all will work ok.

Can I use any API to find out when I restart cluster (Gateway recovery) to
check if all alocating shards process is done?
If so I could then execute safely operations like gets and searches
without to be worry about any shard exeption etc.

BTW, you have first to create documents before being able to search for
them.

When I use Java client by:
Node node = nodeBuilder().node();
Client client = node.client();
and using this client to "get operation" like:
GetResponse response = client.prepareGet("twitter", "tweet", "1")
.execute()
.actionGet();
or "search operation" like:
SearchResponse response = client.prepareSearch("test")
.setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
.setQuery(termQuery("multi", "test"))
.setFrom(0).setSize(60).setExplain(true)
.execute()
.actionGet();
I got those exceptions:

Exception in thread "main"
org.elasticsearch.action.NoShardAvailableActionException:
[twitter][2] No shard available for [[twitter][tweet][1]: routing [null]]

Exception in thread "main"
org.elasticsearch.action.search.SearchPhaseExecutionException: Failed to
execute phase [dfs],
total failure; shardFailures {[na][twitter][0]: No active
shards}{[na][twitter][1]: No active shards}{[na][twitter][2]:
No active shards}{[na][twitter][3]: No active
shards}{[na][twitter][4]: No active shards}

Can I do those gets ans searches by my Java client without running first
ES started in windows?
