encode

static String encode(String s)

Deprecated.

decode

static String decode(String s)

Deprecated.

getRescanNode

public static String getRescanNode(ZKWatcher zkw)

Deprecated.

isRescanNode

public static boolean isRescanNode(String name)

Deprecated.

Parameters:

name - the last part in path

Returns:

whether the node name represents a rescan node

isRescanNode

                                   String path)

Deprecated.

Checks if the given path represents a rescan node.

Parameters:

zkw - reference to the ZKWatcher which also contains configuration and constants

path - the absolute path, starts with '/'

Returns:

whether the path represents a rescan node

getSplitLogDir

public static org.apache.hadoop.fs.Path getSplitLogDir(org.apache.hadoop.fs.Path rootdir,
