In the same way that this can hang {*}ImpalaServer::Start(){*}, this can also hang queries in {*}ImpalaServer::ExecuteInternal(){*}, since the call over JNI never returns because the Java threads in *org.apache.impala.service.JniFrontend.getCatalogMetrics()* are stuck here waiting for a *Future* that will never complete:
