Question

I’m using curl to access Hbase with REST. I’m having a problem in inserting data into Hbase. I followed the Stargate documentation but when I follow the same syntax it gives me 400/405 errors of Bad requests and Method not Allowed errors. I have pasted the command below. Please tell me where am I going wrong.

Stargate documentation says

POST /<table>/<row>/<column> (:qualifier)?/<timestamp>
curl -H "Content-Type: text/xml" --data '[...]' http://localhost:8000/test/testrow/test:testcolumn

My curl command is as follows:

curl -H "Content-Type: text/xml" --data '[<CellSet><Row key="111"><Cell column="f1">xyz</Cell></Row></CellSet>]' http://localhost:8080/mytable/row/fam

What is the right way to do this? because this gives me Bad request error.

Also, Im trying the same in a Python client.It gives me ColumnFamilyNotFoundException.I am reading the Xml data that is to be passed to the stargate server from a file.The code is as follows.

url = 'http://localhost:8080/mytable/row/fam'
f = open('example.xml', 'r')
xmlData = f.read()
r = requests.post(url, data=xmlData, headers=headers)

example.xml has the following:

<CellSet>
     <Row key="111">
   <Cell column="fam:column1">
             xyz
         </Cell>
     </Row>
 </CellSet>

It was a very simple mistake. Hbase expects every value in base64 encoding. Tha key as well as columnfamily:column has to be base64 encoded before entering in the xml.
