AWS Hbase: Invalid method name: 'getTableNames'

Question

I am using Hbase 0.94.18 on AWS EMR. I am planning to use HappyBase as it looks very promising. Unfortunately I faced this issue on the very first attempt:

conn = happybase.Connection(port=9200,compat='0.94')

conn.tables()
Traceback (most recent call last):
File "", line 1, in 
File "/usr/local/lib/python2.6/site-packages/happybase/connection.py", line 238, in tables
names = self.client.getTableNames()
File "/usr/local/lib/python2.6/site-packages/happybase/hbase/Hbase.py", line 818, in getTableNames
return self.recv_getTableNames()
File "/usr/local/lib/python2.6/site-packages/happybase/hbase/Hbase.py", line 833, in recv_getTableNames
raise x
thrift.Thrift.TApplicationException: Invalid method name: 'getTableNames'

Can you please help me?

Are you sure the interface you're connecting to is a HBase Thrift1 service? It looks like a protocol incompatibility...

Ahh okkay Thank you. I will start thrift1 server and try – Ayan Guha Sep 23 '15 at 00:21
Genius, I changed thrift version to 1 and it solved the problem – MCMZL Jul 18 '18 at 17:13
As of today, it seems that `happybase` is using thrift2: https://github.com/python-happybase/happybase/blob/master/requirements.txt#L2 – ItayB Apr 25 '21 at 14:27
nope, don't confuse hbase thrift api versioning with python client libraries for the thrift protocol – wouter bolsterlee Apr 26 '21 at 17:19

When using "hbase thrift2 start -threadpool" I get the same error.

When using "thrift" (i.e. thrift 1) the error disappears.

This is caused by accessing the thrift 2 interface using happybase's thrift 1 implementation.
