-----------------------------

             Summary: Make sure no resource leak of RocksObject
                 Key: FLINK-14926
                 URL: https://issues.apache.org/jira/browse/FLINK-14926
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / State Backends
    Affects Versions: 1.9.1, 1.8.2, 1.7.2, 1.6.4
            Reporter: Yu Li


When investigating FLINK-14484 to allow setting {{WriteBufferManager}} via options, we find it necessary to supply a {{close}} method in {{OptionsFactory}} to make sure resources configured in options like {{WriteBufferManager}} could/would be released.

What's more, we're having potential risk of resource leak in {{PredefinedOptions}} such as the created [BloomFilter instance|https://github.com/apache/flink/blob/e14bd50fed42e89674ba9d01a231d5c5e59f490c/flink-state-backends/flink-statebackend-rocksdb/src/main/java/org/apache/flink/contrib/streaming/state/PredefinedOptions.java#L155] is never closed (regression caused by FLINK-7220 changes), and we should also fix this and add a {{close}} method in {{PredefinedOptions}}
