----------------------------------
Hi, [~zhangduo], patch for this issue has been submitted. Please review it when
you have time.
Test with python 3.12.8 and thrift 0.14.1, it works well.
First, we use the following commands to start the HBase cluster and Thrift
service.
{code:language=|borderStyle=solid|theme=RDark|linenumbers=true|collapse=false}
./bin/start-hbase.sh
./bin/hbase thrift2 start
{code}
Then run the {{DemoClient.py}} script in the {{thrift2}} directory using the
following command:
{code:language=|borderStyle=solid|theme=RDark|linenumbers=true|collapse=false}
python thrift2/DemoClient.py [localhost] [9090]
{code}
The output is as follows:
{code:language=|borderStyle=solid|theme=RDark|linenumbers=true|collapse=false}
Thrift2 Demo
Usage: DemoClient [host=localhost] [port=9090]
This demo assumes you have a table called "example" with a column family called
"family1"
Putting: TPut(row=b'row1', columnValues=[TColumnValue(family=b'family1',
qualifier=b'qualifier1', value=b'value1', timestamp=None, tags=None,
type=None)], timestamp=None, attributes=None, durability=None,
cellVisibility=None)
Getting: TGet(row=b'row1', columns=None, timestamp=None, timeRange=None,
maxVersions=None, filterString=None, attributes=None, authorizations=None,
consistency=None, targetReplicaId=None, cacheBlocks=None, storeLimit=None,
storeOffset=None, existence_only=None, filterBytes=None)
Result: TResult(row=b'row1', columnValues=[TColumnValue(family=b'family1',
qualifier=b'qualifier1', value=b'value1', timestamp=1765178855388, tags=None,
type=4)], stale=False, partial=False)
row = row1
family = family1
qualifier = qualifier1
value = value1
timestamp = 1765178855388

> 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.
