     [ https://issues.apache.org/jira/browse/HBASE-18825?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Duo Zhang updated HBASE-18825:
------------------------------
    Release Note: 
Cleanup the StoreFile interface.

The metadata keys are moved to HStoreFile.

These methods are removed:
CacheConfig getCacheConf();
byte[] getMetadataValue(byte[] key);
boolean isCompactedAway();
boolean isReferencedInReads();
void initReader() throws IOException;
StoreFileScanner getPreadScanner(boolean cacheBlocks, long readPt, long scannerOrder, boolean canOptimizeForNonNullColumn);
StoreFileScanner getStreamScanner(boolean canUseDropBehind, boolean cacheBlocks, boolean isCompaction, long readPt, long scannerOrder, boolean canOptimizeForNonNullColumn) throws IOException;
StoreFileReader getReader();
void closeReader(boolean evictOnClose) throws IOException;
void markCompactedAway();
void deleteReader() throws IOException;

Notice that they are still available in HStoreFile. And the return value of getFirstKey and getLastKey are changed from Cell to Optional<Cell> to better indicate that they may not be available.
