我正在慢慢学习acumulo命令，并且在运行apache hello world示例时遇到了一些问题，该示例将10k行（50k个条目）批量摄取到acumulo中。https://accumulo.apache.org/1.7/examples/
我使用uno构建来启动和运行hdfs、zookeeper和acumulo（2.0）。我可以使用web浏览器连接到hadoop和accumulo。我可以通过shell登录accumulo，并成功地创建了表hellotable。apache示例中的指令接着说要启动用batchwriter批量插入的java程序。通用示例命令如下：

$ ./bin/accumulo org.apache.accumulo.examples.simple.helloworld.InsertWithBatchWriter instance zookeepers username password hellotable

根据已安装的信息，我正在运行以下命令：
我的acumulo示例是uno，我的用户名是root，密码是secret

$ accumulo org.apache.accumulo.examples.simple.helloworld.InsertWithBatchWriter uno zookeepers root secret hellotable

运行该命令时，会出现以下与java和accumulo相关的错误：

OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

如何修改命令以干净地执行？
谢谢
