nsivabalan opened a new pull request #4762:
URL: https://github.com/apache/hudi/pull/4762
## What is the purpose of the pull request
Adding support to setting custom scheduler spark configs for streaming sink.
Users have to set "spark.scheduler.allocation.file=/sample_alloc_file" when
they launch the spark-shell to leverage this.
sample file
```
<?xml version="1.0"?>
<allocations>
<pool name="sparkdatasourcewrite">
<schedulingMode>FAIR</schedulingMode>
<weight>4</weight>
<minShare>2</minShare>
</pool>
<pool name="hoodiecompact">
<schedulingMode>FAIR</schedulingMode>
<weight>3</weight>
<minShare>1</minShare>
</pool>
</allocations>
```
The poolname is hardcoded within hudi and so users are expected to match the
pool names as is.
