Closes the iterator so that the underlying streams can be closed.
|
org.apache.hadoop.io.DataInputBuffer |
getKey()
Gets the current raw key.
|
org.apache.hadoop.util.Progress |
getProgress()
Gets the Progress object; this has a float (0.0 - 1.0)
indicating the bytes processed by the iterator so far
|
org.apache.hadoop.io.DataInputBuffer |
getValue()
Gets the current raw value.
|
boolean |
next()
Sets up the current key and value (for getKey and getValue).
