You need to have either Java8 or Java11 installed locally to start a Java expansion service to expand your SqlTransforms into Java SDK transforms. This is pipeline construction different from later pipeline execution and could be where your issue occurred.
I'm using SQL transform of apache_beam python and deploy to Dataflow by Flex Template. The pipeline show the error: Java must be installed on this system to use. I know the SQL transform of beam python using Java, I researched the way to add Java to pipeline but all failed.
Can you give any advice on how to fix this error? Thank a lot.
