# Instructions:
|
|
|
|
|
# 1. Run Thrift to generate the python module hbase
|
|
|
|
|
# thrift --gen py ../../../src/main/resources/org/apache/hadoop/hbase/thrift2/hbase.thrift
|
|
|
|
|
# 2. Create a directory of your choosing that contains:
|
|
|
|
|
# a. This file (DemoClient.py).
|
|
|
|
|
# b. The directory gen-py/hbase (generated by instruction step 1).
|
|
|
|
|
# 3. pip install thrift==0.7.0
|
|
|
|
|
# 4. Create a table call "example", with a family called "family1" using the hbase shell.
|
|
|
|
|
# 5. Start the hbase thrift2 server
|
|
|
|
|
# bin/hbase thrift2 start
|
|
|
|
|
# 6. Execute {python DemoClient.py}.
