> In a multi-writer scenario, not all writers might set the enable clustering config. 
> BaseSparkCommitActionExecutor
> {code:java}
> private JavaRDD<HoodieRecord<T>> clusteringHandleUpdate(JavaRDD<HoodieRecord<T>> inputRecordsRDD) {
>   if (config.isClusteringEnabled()) {
>     Set<HoodieFileGroupId> fileGroupsInPendingClustering =
>         table.getFileSystemView().getFileGroupsInPendingClustering().map(entry -> entry.getKey()).collect(Collectors.toSet());
>     UpdateStrategy updateStrategy = (UpdateStrategy)ReflectionUtils

> When clustering is scheduled and being executed by writer1, writer2 could go ahead and make updates to the same file group w/o any issues, given writer2 did not enable clustering in the write config.
