Hello. I would like to ask for help with my sample code using portable runner using apache flink. I was able to work out the wordcount.py using this page.
https://beam.apache.org/roadmap/portability/ I got below two files under /tmp. -rw-r--r-- 1 ywatanabe ywatanabe 185 Sep 12 19:56 py-wordcount-direct-00001-of-00002 -rw-r--r-- 1 ywatanabe ywatanabe 190 Sep 12 19:56 py-wordcount-direct-00000-of-00002 Then I wrote sample code with below steps. 1.Install apache_beam using pip3 separate from source code directory. 2. Wrote sample code as below and named it "test-protable-runner.py". Placed it separate directory from source code. ----------------------------------------------------------------------------------- (python) ywatanabe@debian-09-00:~$ ls -ltr total 16 drwxr-xr-x 18 ywatanabe ywatanabe 4096 Sep 12 19:06 beam (<- source code directory) -rw-r--r-- 1 ywatanabe ywatanabe 634 Sep 12 20:25 test-portable-runner.py ----------------------------------------------------------------------------------- 3.
