> The RemoteStorageManager.fetchIndex returns an inputStream, and the resource should be released explicitly. I found some places we forgot to close it. Ex: [here|https://github.com/apache/kafka/blob/6677bf7b21ae7022ac094a39ae2f640f95cc30b9/core/src/main/java/kafka/server/TierStateMachine.java#L153], [here|https://github.com/apache/kafka/blob/6677bf7b21ae7022ac094a39ae2f640f95cc30b9/core/src/main/java/kafka/server/TierStateMachine.java#L168], and more
>  
> Note, we also need to check RemoteStorageManager.fetchLogSegment usage.
