singhravidutt opened a new pull request, #23933:
URL: https://github.com/apache/flink/pull/23933

   ## What is the purpose of the change
   Shade the guava version required specifically by google-cloud-storage.
   
   ## Brief change log
   
   Introduced dependency on guava version(`31.1-jre`) required by 
`google-cloud-storage`. Upgrade of `google-cloud-storage` lead to runtime 
failure because of new functionalities added in `31.1-jre`.
   
   This change pins guava version to the one required by storage client 
specifically in `flink-gs-fs-hadoop`, leaving all other filesystem 
implementation untouched.
   
   ## Verifying this change
   
   This change is already covered by existing tests. These tests pass with the 
new version.
   ```
   mvn -Pfast -pl flink-filesystems/flink-gs-fs-hadoop clean test
   ```
   
   Created a cluster by replacing binaries specific to `flink-gs-fs-hadoop` and 
ran the following job
   
   ```
   gcloud dataproc jobs submit flink --cluster <cluster-name> --region 
us-central1 --jar file:///usr/lib/flink/examples/streaming/WordCount.jar -- 
--input gs://vinaylondhe-public/word_count/word_count.txt --output 
gs://vinaylondhe-public/rdsingh_wc_output
   ```
   
   Earlier it was failing with following error
   
   ```
   Caused by: java.lang.NoSuchMethodError: 
'com.google.common.collect.ImmutableMap 
com.google.common.collect.ImmutableMap$Builder.buildOrThrow()'
   ```
   
   Execution for the same job successful now with these changes.
