协议错误：没有协议版本头

Question

I have hortonworks cluster with versions as below:

• hbase = 1.1.2
• happybase=1.1.0
• hortonworks hadoop cluster = HDP-2.6.2.0

When I try to run simple example:

import happybase
server = "server-address"
connection = happybase.Connection(server)
print connection.tables()

I got this exception:

Traceback (most recent call last):
  File "/Users/psobolewski/hbase_urls.py", line 19, in <module>
    print connection.tables()
  File "/Library/Python/2.7/site-packages/happybase/connection.py", line 242, in tables
    names = self.client.getTableNames()

尝试更改 port=2181 并检查 hbase-site.xml
