N1QL on a single node

i’m running Couchbase Server 3.0.1 on a test environment composed by two nodes. I’m using the java client sdk v 2.0.2 and i want to run some n1ql query by sdk. I’ve installed the N1QL engine on just a node of two, but when the query is executed it returns a ConnectionTimeoutException. Do I need to install on both the nodes in my cluster?

Thank in advance,

Hi Antonio,

Can you try running cbq-engine on both nodes, and see if the error continues? Note that if you are using N1QL DP4, you should probably upgrade to the latest Java SDK.
