I'm using happybase to connect to HBase. So far the connection is fine. We have thrift up and running. I'm able to connect to the table (AFAIK), but when I try to scan the table I get TTransportException: TSocket read 0 bytes. Here is the code that I am using.
import happybase
import json
connection = happybase.Connection('ipaddress', '22')
table = connection.table('rawdataingestion')
for key, data in table.scan():
print key, data
break
I'm using break here so it doesn't print out a google rows. I just want to see that it's making a connection and bringing in the data.
Here's the error.
