Hi All, Today we got Below exception in webapp layer ( jboss ) **[SERVICE\_UNAVAILABLE/1/state not recovered / initialized];[SERVICE\_UNAVAILABLE/2/no master];** we are using elasticsearch.jar ( transport client ) to connect es from jboss. elasticsearch version is 1.3.7 1. We initiated the start command at **2016-10-18 17:52:04,263** 2. Node started to listen at **[2016-10-18 17:52:06,491]**[INFO][transport] [node1] bound\_address {inet[/XX.XX.XX.XX:YYYY]}, publish\_address {inet[/XX.XX.XX.XX:YYYY]} 3. we got exception at **2016-10-18 17:52:08,753** 😓 4. Node Joined the cluster at **[2016-10-18 17:52:09,611]**[INFO][cluster.service] [node1] detected\_master Is there any to avoid the listen before the added into cluster. [or] How to make the node to listen req after join the cluster Please help on this!!! ---

Hi @Selvam_ayyanar, when did this problem happen (start of the appliation)? Can you show some code? Did you do anything on Elasticsearch side? Daniel ---

Hi @danielmitterdorfer Thanks for the reply This exception happen in-between the node startup and node joins the cluster. > from application we tried to index a document, after joining cluster it is fine. > also after stopping node it is able to perform index operation on another node( using sniff ) > when we bring back the node, it throws the exception before the node joins into the cluster ---

Hi @Selvam_ayyanar, > [@Selvam\_ayyanar](#): > > This exception happen in-between the node startup and node joins the cluster. by "node" you refer to your application in JBoss that is connected via the transport client to your Elasticsearch cluster? Daniel ---

Hi @Selvam_ayyanar, great, exactly what I had expected. You just need to catch `ClusterBlockException`, check if it is retrieable and then do so. A very rough sketch (untested but I hope you get the idea): ```auto int numberOfRetries = 3; while (numberOfRetries > 0) { try { return client.doSomeAction(); } catch (ClusterBlockException ex) { if (ex.retryable()) { numberOfRetries--; // wait a bit with the next retry Thread.sleep(1000L); } else { //not retryable -> bail throw ex; } } } ``` Edit: I figured you should also wait a little bit between retries. 🙂 Daniel ---
