方法详细资料

createWriter

public static FSHLogProvider.Writer createWriter(org.apache.hadoop.conf.Configuration conf,
                                                 org.apache.hadoop.fs.FileSystem fs,
                                                 org.apache.hadoop.fs.Path path,
                                                 boolean overwritable)
                                          throws IOException

Public because of FSHLog. Should be package-private

参数:

overwritable - if the created writer can overwrite. For recovered edits, it is true and for WAL it is false. Thus we can distinguish WAL and recovered edits by this.

抛出:

IOException

createWriter

public static FSHLogProvider.Writer createWriter(org.apache.hadoop.conf.Configuration conf,
                                                 org.apache.hadoop.fs.FileSystem fs,
                                                 org.apache.hadoop.fs.Path path,
                                                 boolean overwritable,
                                                 long blocksize)
                                          throws IOException

Public because of FSHLog. Should be package-private

抛出:

IOException

createWAL

protected FSHLog createWAL()
                    throws IOException

指定者:

createWAL 在类中 AbstractFSWALProvider<FSHLog>

抛出:

IOException

doInit

protected void doInit(org.apache.hadoop.conf.Configuration conf)
               throws IOException

指定者:

doInit 在类中 AbstractFSWALProvider<FSHLog>

抛出:

IOException
