使用astyanax cassandra驱动程序

Question

我在tomcat上使用astyanax cassandra驱动程序来访问cassandra中的数据。 同时停止tomcat服务器;它挂在从astyanax库开始的线程上。 有没有人遇到过这个问题？

Stacktrace

我确实有代码可以在关机时关闭连接

AstyanaxContext context = (AstyanaxContext)this.contextMap.get(ksName);
            if(context != null) {
                logger.info("shutdown context for keyspace " + ksName);
                ExecutorService asyncExecutor = context.getAstyanaxConfiguration().getAsyncExecutor();
                asyncExecutor.shutdown();

                try {
                    asyncExecutor.awaitTermination(10000L, TIMEUNIT);
                } catch (InterruptedException var6) {
                    ;
                }

                context.shutdown();`
