Ethanlm commented on issue #3094: STORM-3477 switch HDFS blobstore isRemoteBlobExists to use file exist… URL: https://github.com/apache/storm/pull/3094#issuecomment-516570180 Yeah that's what I was thinking about. Based on this, I am thinking it's probably better to check `KeyNotFoundException` inside the `blobExists` function and if it happens, returns false. Then `isRemoteBlobExists` can simply invoke `blobExists` function. Do we want to add a `blobExists` function to `LocalFsBlobStore` too? So they can have the same functionality?
