---------------------------
Summary: Introducing gcpTempLocation that default to tempLocation
Key: BEAM-430
URL: https://issues.apache.org/jira/browse/BEAM-430
Project: Beam
Issue Type: Improvement
Reporter: Pei He
Assignee: Pei He
Priority: Minor
Currently, DataflowPipelineOptions.stagingLocation default to tempLocation.
And, it requires tempLocation to be a gcs path.
Another case is BigQueryIO uses tempLocation and also requires it to be on gcs.
So, users cannot set tempLocation to a non-gcs path with DataflowRunner or
BigQueryIO.
However, tempLocation could be on any file system. For example, WordCount
defaults to output to tempLocation.
The proposal is to add gcpTempLocation. And, it defaults to tempLocation if
tempLocation is a gcs path.
StagingLocation and BigQueryIO will use gcpTempLocation by default.
