Class Summary

Class	Description
AppendRequest	Appends data to one or more columns in HBase, creating the columns if they do not exist.
AtomicIncrementRequest	Atomically increments a value in HBase.
BinaryComparator	A binary comparator used in comparison filters.
BinaryPrefixComparator	A binary comparator used in comparison filters.
BitComparator	A bitwise comparator used in comparison filters.
Bytes	Helper functions to manipulate byte arrays.
Bytes.ByteMap<V>	A convenient map keyed with a byte array.
ClientStats	HBaseClient usage statistics.
ColumnPaginationFilter	A filter, based on the ColumnCountGetFilter, takes two arguments: limit and offset.
ColumnPrefixFilter	Sets a binary prefix to filter results based on the column qualifier.
ColumnRangeFilter	Filters based on a range of column qualifiers.
CompareFilter	A generic scan filter to be used to filter by comparison.
Config	A configuration class that stores key/value pairs as strings similar to the System properties object.
Counter	An atomic counter to replace AtomicLong.
DeleteRequest	Deletes some data into HBase.
DependentColumnFilter	Filters key values based on the existence of a dependent, or reference, column.
FamilyFilter	Filter columns based on the column family.
FilterComparator	Abstract base class for ScanFilter comparators.
FilterList	Combines a list of filters into one.
FirstKeyOnlyFilter	A filter that will only return the first KV from each row.
FuzzyRowFilter	FuzzyRowFilter is a server-side fast-forward filter that allows skipping whole range of rows when scanning.
FuzzyRowFilter.FuzzyFilterPair	Holds a pair of (row_key,fuzzy_mask) to use with FuzzyRowFilter
GetRequest	Reads something from HBase.
GetResultOrException
HBaseClient	A fully asynchronous, thread-safe, modern HBase client.
HBaseRpc	Abstract base class for all RPC requests going out to HBase.
KeyOnlyFilter	A filter that will only return the key component of each KV (the value will be rewritten as empty).
KeyRegexpFilter	Filters rows based on an expression applied to the row key.
KeyValue	A "cell" in an HBase table.
MultiColumnAtomicIncrementRequest	Atomically increments several column values in HBase.
MultipleColumnPrefixFilter	Sets multiple binary prefix filters to filter results based on the column qualifiers.
PutRequest	Puts some data into HBase.
QualifierFilter	Filter columns based on the qualifier.
RegexStringComparator	A regular expression comparator used in comparison filters such as RowFilter, QualifierFilter, and ValueFilter.
RegionClientStats	RegionClient usage statistics.
RegionLocation	A public class that is used to return region hosting information to users via the API.
RowFilter	Filter rows based on the rowkey.
RowLock	An explicit row lock.
RowLockRequest	Acquires an explicit row lock.
ScanFilter	Abstract base class for Scanner filters.
Scanner	Creates a scanner to read data sequentially from HBase.
Scratch
SecureRpcHelper	This base class provides the logic needed to interface with SASL supported RPC versions.
SubstringComparator	A substring comparator used in comparison filters such as RowFilter, QualifierFilter, and ValueFilter.
TimestampsFilter	Filter that returns only cells whose timestamp (version) is in the specified list of timestamps (versions).
ValueFilter	Filter key values based on their value.

Enum Summary

Enum	Description
BitComparator.BitwiseOp	Bit operators.
CompareFilter.CompareOp	Comparison operators.
FilterList.Operator	Operator to combine the list of filters together.

Exception Summary

Exception	Description
BrokenMetaException	Indicates that the .META. or -ROOT- table is corrupted.
CallQueueTooBigException	Exception thrown when the RPC queue on the region server is full and cannot accept new RPCs.
ConnectionResetException	Exception thrown when an RPC was in flight while we got disconnected.
HBaseException	The parent class of all RuntimeException created by this package.
InvalidResponseException	Exception used when the server sends an invalid response to an RPC.
NonRecoverableException	An exception for which it's typically pointless to retry (such as TableNotFoundException).
NoSuchColumnFamilyException	Exception thrown when attempting to use a nonexistent column family.
NotServingRegionException	Exception thrown when we attempted to use a region that wasn't serving from that particular RegionServer.
PleaseThrottleException	This exception notifies the application to throttle its use of HBase.
RecoverableException	An exception for which it's typically useful to retry (such as RegionOfflineException).
RegionMovedException	Exception thrown when we attempted to use a region that was moved from that particular RegionServer to a new one.
RegionOfflineException	Exception thrown when we attempted to find a region, but it wasn't being served by any RegionServer (it's "offline" in HBase speak).
RegionOpeningException	Exception thrown when we attempted to use a region that was is still being opened or altered.
RegionServerAbortedException	Thrown by the region server when it is aborting.
RegionServerStoppedException	Thrown by the region server when it is in shutting down state.
RemoteException	An unclassified exception that occurred on the server side.
RpcTimedOutException	An exception where we haven't received a response for an in-flight RPC
ServerNotRunningYetException	Thrown by the region server when it is not yet running.
TableNotFoundException	Exception thrown when an attempt to use an inexistent table was made.
UnknownRowLockException	Exception thrown when we try to use an invalid or expired RowLock.
