Andrew Wong updated KUDU-3227:
------------------------------
Labels: newbie (was: )
> Improve client error message when not a part of a trusted subnet
> ----------------------------------------------------------------

> Key: KUDU-3227
> URL: https://issues.apache.org/jira/browse/KUDU-3227
> Project: Kudu
> Issue Type: Improvement
> Components: client
> Reporter: Andrew Wong
> Priority: Major
> Labels: newbie

> I recently saw a case where the Java application spit out this error, failing
> to connect to the cluster:
> {code:java}
> Caused by: org.apache.kudu.client.NoLeaderFoundException: Master config
> (master:7051) has no leader. Exceptions received:
> org.apache.kudu.client.RecoverableException: connection disconnected
> at
> org.apache.kudu.client.ConnectToCluster.incrementCountAndCheckExhausted(ConnectToCluster.java:289)
> at
> org.apache.kudu.client.ConnectToCluster.access$100(ConnectToCluster.java:49)
> at
> org.apache.kudu.client.ConnectToCluster$ConnectToMasterErrCB.call(ConnectToCluster.java:365)
> at
> org.apache.kudu.client.ConnectToCluster$ConnectToMasterErrCB.call(ConnectToCluster.java:354)
> at com.stumbleupon.async.Deferred.doCall(Deferred.java:1280)
> at com.stumbleupon.async.Deferred.runCallbacks(Deferred.java:1259)
> at com.stumbleupon.async.Deferred.handleContinuation(Deferred.java:1315)
> at com.stumbleupon.async.Deferred.doCall(Deferred.java:1286)
> {code}
> Other clients (i.e. Impala) were able to run similar queries without such
> errors, so it seemed localized to this one application. This was odd given
> the error message complains about not having a Master leader, a property of
> the cluster, not the client.
> Inspecting the master logs, it was relatively clear that
> {{--trusted_subnets}} was likely to blame (the server-side warning message
> that is spit out mentions it by name). It would be nice if this was obvious
> in the clients as well.
