Method Detail

setupLocal

public void setupLocal()

Description copied from class: MRTask

Override to do any remote initialization on the 1st remote instance of this object, for initializing node-local shared data structures.

Overrides:

setupLocal in class MRTask<FileIntegrityChecker>

reduce

public void reduce(FileIntegrityChecker o)

Description copied from class: MRTask

Override to combine results from 'mrt' into 'this' MRTask. Both 'this' and 'mrt' are guaranteed to either have map() run on them, or be the results of a prior reduce(). Reduce is optional if, e.g., the result is some output vector.

Overrides:

reduce in class MRTask<FileIntegrityChecker>

check

public static FileIntegrityChecker check(java.io.File r)

size

public int size()

syncDirectory

public Key syncDirectory(java.util.ArrayList<java.lang.String> files,
                         java.util.ArrayList<java.lang.String> keys,
                         java.util.ArrayList<java.lang.String> fails,
                         java.util.ArrayList<java.lang.String> dels)
