I'm using happybase to connect to my Hbase database. I made a sample table called 'irisSample'. Here's the part of the code that I'm having trouble with-
import happybase
from happybase import *
import json
connection = happybase.Connection('<ip-address>', '9090')
table = connection.table('irisSample')
n = 0
x = 1
for u in y:
data = {'petalWidth':points['petalWidth'][n], 'sepalLength':points['sepalLength'][n],
'petalLength':points['petalLength'][n], 'label': u}
row = 'row' + str(x)
table.put(row, {'flowers': str(data)})
n += 1
x += 1
And I get the following.
TApplicationException Traceback (most recent call last)

I've also tried json.dumps(data)
instead of str(data)
which threw the same exception.
From what I'm gathering it seems more like a Thrift problem but I could be wrong. I may have to look at starbase instead. I don't know, that's why I'm asking you guys.
I found the answer here. It required a REST framework to be running on an unused port. I then connected to that port and was able to see the list of all the tables in Hbase and insert data into the database. The command is ./hbase-daemon.sh start rest -p <unused port number>
. I couldn't find the answer anywhere and no one even commented for a few days so I hope this helps you! Here's the code. I ended up using starbase
.
import starbase
from starbase import Connection
c = Connection(host='<ip-address>', port=8000)
8000 is the default port by the way.
t = c.table('irisSample')
for flower in range(len(labels)):
data = {'petalWidth':X[flower][3], 'petalLength':X[flower][2],
'sepalLength':X[flower][0], 'sepalWidth':X[flower][1], 'cluster': labels[flower]}
n += 1
row = 'row' + str(n)
t.insert(row, {'flowers': data})
