Summary: Thrift2 DemoClient.py
Key: HBASE-23644
URL: https://issues.apache.org/jira/browse/HBASE-23644
Project: HBase
Issue Type: Improvement
Affects Versions: 2.2.2
Reporter: Madhukumar
Fix For: 2.2.4
Attachments: DemoClient.py
*hbase-examples/py*
I tried to connect to hbase thrift2 server with python with given demo file
DemoClient.py. Issue is the DemoClient.py is not updated for python 3.X.
Python 2.X support has ended. Even the github vesrion is not updated, happy to
update it.
I'm using python 3.8. {color:#ff0000}_Attached file for DemoClient.py for
python 3.X._ I'm new to Jira and hbase. {color} __
hbase.thrift file that was used to generate gen-py in 2.2.22 release examples
does seem like this file
hbase-src-2.2.2/hbase-thrift/src/main/resources/org/apache/hadoop/hbase/thrift2/hbase.thrift.
_I'm looking for hbase.thrift that was used to get gen-py in py examples. If
you can point me to that, that will be great._
{color:#172b4d}If you generate gen-py using thrift compiler 0.13, this is error
that I'm getting when running DemoClient.py, {color}

{color:#172b4d}Please note that I'm using 0.13 py client package for thrift. It
does not work with thrift==0.9.3 as well.{color}
Out of the box gen-py that came with 2.2.2 source examples has the following
issues working with thrift 0.13 py packages and it is also not code generated
for python 3.0 but 2.0.
* ttypes.py > self.__dict.__iteritems() does not work in python 3.0, so it
need to be items
* xrange does not work in python 3.0 so all that need to be range
thrift compiler 0.13 was available at this point from apache/thrift. It
generates the files for python 2.0 it seems because of above two issues because
hbase.thrift that is src (link given above), not sure what can be done about
this.
So, I have 0.13 python thrift package which works with python 3.0.
DemoClient.py updated to 3.0 but issue is gen-py generation. I don't want to
edit these generated py files, so if right hbase.thrift file that works with
thrift 0.13.0 compiler, that will be great. Thanks.
