org.apache.hadoop.hbase.coprocessor中WALCoprocessorEnvironment的使用

类型变量类型为WALCoprocessorEnvironment的org.apache.hadoop.hbase.coprocessor中的方法参数

限定符和类型	方法和说明
void	WALObserver.postWALRoll(ObserverContext<? extends WALCoprocessorEnvironment> ctx, org.apache.hadoop.fs.Path oldPath, org.apache.hadoop.fs.Path newPath) Called after rolling the current WAL
void	BaseWALObserver.postWALRoll(ObserverContext<? extends WALCoprocessorEnvironment> ctx, org.apache.hadoop.fs.Path oldPath, org.apache.hadoop.fs.Path newPath)
void	WALObserver.postWALWrite(ObserverContext<? extends WALCoprocessorEnvironment> ctx, HRegionInfo info, WALKey logKey, WALEdit logEdit) Called after a WALEdit is writen to WAL.
void	BaseWALObserver.postWALWrite(ObserverContext<? extends WALCoprocessorEnvironment> ctx, HRegionInfo info, WALKey logKey, WALEdit logEdit) Implementers should override this method and leave the deprecated version as-is.
void	WALObserver.postWALWrite(ObserverContext<WALCoprocessorEnvironment> ctx, HRegionInfo info, HLogKey logKey, WALEdit logEdit) 已过时。 use WALObserver.postWALWrite(ObserverContext, HRegionInfo, WALKey, WALEdit)
void	BaseWALObserver.postWALWrite(ObserverContext<WALCoprocessorEnvironment> ctx, HRegionInfo info, HLogKey logKey, WALEdit logEdit)
void	WALObserver.preWALRoll(ObserverContext<? extends WALCoprocessorEnvironment> ctx, org.apache.hadoop.fs.Path oldPath, org.apache.hadoop.fs.Path newPath) Called before rolling the current WAL
void	BaseWALObserver.preWALRoll(ObserverContext<? extends WALCoprocessorEnvironment> ctx, org.apache.hadoop.fs.Path oldPath, org.apache.hadoop.fs.Path newPath)
boolean	WALObserver.preWALWrite(ObserverContext<? extends WALCoprocessorEnvironment> ctx, HRegionInfo info, WALKey logKey, WALEdit logEdit) Called before a WALEdit is writen to WAL.
boolean	BaseWALObserver.preWALWrite(ObserverContext<? extends WALCoprocessorEnvironment> ctx, HRegionInfo info, WALKey logKey, WALEdit logEdit) Implementers should override this method and leave the deprecated version as-is.
boolean	WALObserver.preWALWrite(ObserverContext<WALCoprocessorEnvironment> ctx, HRegionInfo info, HLogKey logKey, WALEdit logEdit) 已过时。 use WALObserver.preWALWrite(ObserverContext, HRegionInfo, WALKey, WALEdit)
