there is a single test failure from the report: https://github.com/GoogleCloudPlatform/DataflowTemplates/pull/2050/checks?check_run_id=33950822829

expected to contain hash: 81f7b7afd932b4754caaa9ba6ced7a8bcb2cbfec6857cf823e4d112125c6e939
but was                 : [org.apache.beam.it.gcp.artifacts.GcsArtifact@40673c72]
	at com.google.cloud.teleport.templates.BulkCompressorIT.baseCompress(BulkCompressorIT.java:85)
	at com.google.cloud.teleport.templates.BulkCompressorIT.testCompressGzip(BulkCompressorIT.java:55)

This is expected. The original assert was too strict, see

Thanks! Just have a minor comment, could be follow up (so no need to push new commit that triggers all tests)
