fetch_all_rows() returns None on default arguments.

It works with argument scanner_config={}. The default value '' can't be parsed by Java side, and causes an HTTP Error 500.

Hey,

Thanks for reporting this. I'll check the issue and make a fix soon.

Best regards,

@hanwentao:

Hey, the following code works for me:

from starbase import Connection
c = Connection()
t = c.table('messages')
[row for row in t.fetch_all_rows()]

Could you provide some more information on the issue?

[hanwentao]

I think the problem lies on the server side. The version of HBase I used is 0.96.1, and it can't parse "" as a JSON object.

@hanwentao

Confirmed on HBase 0.98.1-cdh5.1.0 (Cloudera).

{u'JVM': u'Oracle Corporation 1.7.0_55-24.55-b03',
u'Jersey': u'1.8',
u'OS': u'Linux 2.6.32-431.23.3.el6.x86_64 amd64',
u'REST': u'0.0.2',
u'Server': u'jetty/6.1.26.cloudera.2'}

Also happened to me with HBase 0.98.4. With default parameters I get an error, with a no-op scanner_config parameter it works.

I track the source and find that:
if scanner_config == "", the request data is ""
but the Content-type of starbase is application/json, so the http request will pass data "" to hbase rest server, the error occurs.
if scanner_config == {}, the request data is "{}" and it can work

ps: if scanner_config == '' , it also can work because python will convert content type to xml/text, and you also can define the batch size of scanner.

Thanks for tracking this down. I'll fix it ASAP.
