我从以下位置部署了最新版本的 Apache Impala：
http://www.apache.org/dyn/closer.cgi?action=download&filename=impala/3.3.0/apache-impala-3.3.0.tar.gz
并查看我使用的端口netstat -- listen（见下文）。我没有使用 21000，而是尝试使用 31000，因为 Impala 使用的端口如下所述：
https://www.cloudera.com/documentation/enterprise/5-14-x/topics/impala_ports.html
但无法从位于另一台计算机上的 impala-shell 连接（尝试了 21000 但也失败了）。我是不是漏掉了什么？impala 守护进程正在运行，就像我
root@bb9f4792e21d:/opt/Impala/bin# ps -ef | grep -i impalad
root 23067 1 0 15:31 pts/0 00:00:00 grep --color=auto -i impalad
我可以看到它正在运行。
