All Classes Interface Summary Class Summary Enum Summary Exception Summary
Class	Description
CopyCommitter	The CopyCommitter class is DistCp's OutputCommitter implementation.
CopyFilter	Interface for excluding files from DistCp.
CopyListing	The CopyListing abstraction is responsible for how the list of sources and targets is constructed, for DistCp's copy function.
CopyListing.AclsNotSupportedException
CopyListing.XAttrsNotSupportedException
CopyListingFileStatus	CopyListingFileStatus is a view of `FileStatus`, recording additional data members useful to distcp.
CopyMapper	Mapper class that executes the DistCp copy operation.
CopyMapper.ChecksumComparison	Indicates the checksum comparison result.
CopyMapper.Counter	Hadoop counters for the DistCp CopyMapper.
CopyOutputFormat<K,V>	The CopyOutputFormat is the Hadoop OutputFormat used in DistCp.
DistCp	DistCp is the main driver-class for DistCpV2.
DistCpConstants	Utility class to hold commonly used constants.
DistCpContext	This is the context of the distcp at runtime.
DistCpOptions	The Options class encapsulates all DistCp options.
DistCpOptions.Builder	The builder of the `DistCpOptions`.
DistCpOptions.FileAttribute	File attributes for preserve.
DistCpOptionSwitch	Enumeration mapping configuration keys to distcp command line options.
DistCpUtils	Utility functions used in DistCp.
DynamicInputFormat<K,V>	DynamicInputFormat implements the "Worker pattern" for DistCp.
DynamicRecordReader<K,V>	The DynamicRecordReader is used in conjunction with the DynamicInputFormat to implement the "Worker pattern" for DistCp.
FileBasedCopyListing	FileBasedCopyListing implements the CopyListing interface, to create the copy-listing for DistCp, by iterating over all source paths mentioned in a specified input-file.
FileListingEntry
GlobbedCopyListing	GlobbedCopyListing implements the CopyListing interface, to create the copy listing-file by "globbing" all specified source paths (wild-cards and all.)
OptionsParser	The OptionsParser parses out the command-line options passed to DistCp, and interprets those specific to DistCp, to create an Options object.
ProducerConsumer<T,R>	ProducerConsumer class encapsulates input and output queues and a thread-pool of Workers that loop on WorkRequest<T> inputQueue and for each consumed WorkRequest Workers invoke WorkRequestProcessor.processItem() and output resulting WorkReport<R> to the outputQueue.
RegexCopyFilter	A CopyFilter which compares Java Regex Patterns to each Path to determine whether a file should be copied.
RegexpInConfigurationFilter	Implementation of regex based filter for DistCp.
RetriableCommand	This class represents commands that be retried on failure, in a configurable manner.
RetriableDirectoryCreateCommand	This class extends Retriable command to implement the creation of directories with retries on failure.
RetriableFileCopyCommand	This class extends RetriableCommand to implement the copy of files, with retries on failure.
RetriableFileCopyCommand.CopyReadException	Special subclass of IOException.
SimpleCopyListing	The SimpleCopyListing is responsible for making the exhaustive list of all files/directories under its specified list of input-paths.
ThrottledInputStream	The ThrottleInputStream provides bandwidth throttling on a specified InputStream.
TrueCopyFilter	A CopyFilter which always returns true.
UniformSizeInputFormat	UniformSizeInputFormat extends the InputFormat class, to produce input-splits for DistCp.
WorkReport<T>	WorkReport<T> is a simple container for items of class T and its corresponding retry counter that indicates how many times this item was previously attempted to be processed.
WorkRequest<T>	WorkRequest<T> is a simple container for items of class T and its corresponding retry counter that indicates how many times this item was previously attempted to be processed.
WorkRequestProcessor<T,R>	Interface for ProducerConsumer worker loop.
