LadyForest opened a new pull request, #22818:
URL: https://github.com/apache/flink/pull/22818
## What is the purpose of the change
This PR extends the `COMPILE PLAN` statement to read/write from/to Flink
`FileSystem`.
## Brief change log
This PR contains two commits
- f397fe6c Fix the issue that the current `COMPILE PLAN` statement cannot
write the plan to a local path if its parent dir does not exist.
- 8f744a4e Extend the `COMPILE AND EXECUTE PLAN` statement to read from a
remote plan with URI like `hdfs://` or `s3://`. The impl leverages the power of
`ResourceManager` to stage a local file copy, which will be cleaned up when the
SQL gateway or client close.
## Verifying this change
This change added tests and can be verified as follows:
- The first commit can be verified by rolling back src changes
`ExecNodeGraphInternalPlan` and running `CompiledPlanITCase`.
- The second commit adds tests as follows:
- `FlinkSqlParserImplTest` verifies the syntax works as expected
- `ResourceManagerTest` verifies the newly introduced methods work as
expected
- `insert.q` verifies the changes work on the absolute path without the
scheme, relative path without the scheme, and absolute path with the scheme for
the local file system.
- `CompileAndExecuteRemotePlanITCase` is an E2E case to verify the changes
work as expected for HDFS remote path.
