方法详细资料

getName

TableName getName()

Gets the fully qualified table name instance of this table.

getConfiguration

org.apache.hadoop.conf.Configuration getConfiguration()

Returns the Configuration object used by this instance.

The reference returned is not a copy, so any change made to it will affect this instance.

getTableDescriptor

HTableDescriptor getTableDescriptor()
                                    throws IOException

Gets the table descriptor for this table.

抛出:

IOException - if a remote or network exception occurs.

exists

boolean exists(Get get)
               throws IOException

Test for the existence of columns in the table, as specified by the Get.

This will return true if the Get matches one or more keys, false if not.

This is a server-side call so it prevents any data from being transfered to the client.

参数:

get - the Get

返回:

true if the specified Get matches one or more keys, false if not

抛出:

IOException - e

existsAll

boolean[] existsAll(List<Get> gets)
                    throws IOException

Test for the existence of columns in the table, as specified by the Gets.

This will return an array of booleans. Each value will be true if the related Get matches one or more keys, false if not.

This is a server-side call so it prevents any data from being transferred to the client.

参数:

gets - the Gets

返回:

Array of boolean. True if the specified Get matches one or more keys, false if not.

抛出:

IOException - e

batch

void batch(List<? extends Row> actions,

Method that does a batch call on Deletes, Gets, Puts, Increments, Appends, RowMutations The ordering of execution of the actions is not defined. Meaning if you do a Put and a Get in the same batch(java.util.List<? extends org.apache.hadoop.hbase.client.Row>, java.lang.Object[]) call, you will not necessarily be guaranteed that the Get returns what the Put had put.

参数:

actions - list of Get, Put, Delete, Increment, Append, RowMutations

results - Empty Object[], same size as actions. Provides access to partial results, in case an exception is thrown. A null in the result array means that the call for that action failed, even after retries

                        Durability durability)
                          throws IOException

Atomically increments a column value. If the column value already exists and is not a big-endian long, this could throw an exception. If the column value does not yet exist it is initialized to amount and written to the specified column.

Setting durability to Durability.SKIP_WAL means that in a fail scenario you will lose any increments that have not been flushed.

coprocessorService

CoprocessorRpcChannel coprocessorService(byte[] row)

Creates and returns a RpcChannel instance connected to the table region containing the specified row. The row given does not actually have to exist. Whichever region would contain the row based on start and end keys will be used. Note that the row parameter is also not passed to the coprocessor handler registered for this protocol, unless the row is separately passed as an argument in the service request. The parameter here is only used to locate the region used to handle the call.

The obtained RpcChannel instance can be used to access a published coprocessor Service using standard protobuf service invocations:

 CoprocessorRpcChannel channel = myTable.coprocessorService(rowkey);
 MyService.BlockingInterface service = MyService.newBlockingStub(channel);
 MyCallRequest request = MyCallRequest.newBuilder()
     ...
     .build();
 MyCallResponse response = service.myCall(null, request);
 

参数:

row - The row key used to identify the remote region location

返回:

A CoprocessorRpcChannel instance

R - the response type for the coprocessor Service method

参数:

methodDescriptor - the descriptor for the protobuf service method to call.

request - the method call parameters

startKey - start region selection with region containing this row. If null, the selection will start with the first table region.

endKey - select regions up to and including the region containing this row. If null, selection will continue through the last table region.

Atomically checks if a row/family/qualifier value matches the expected value. If it does, it performs the row mutations. If the passed value is null, the check is for the lack of column (ie: non-existence)

参数:

row - to check

family - column family to check

qualifier - column qualifier to check

compareOp - the comparison operator

value - the expected value

mutation - mutations to perform if check succeeds

返回:

true if the new put was executed, false otherwise

setOperationTimeout

void setOperationTimeout(int operationTimeout)

Set timeout (millisecond) of each operation in this Table instance, will override the value of hbase.client.operation.timeout in configuration. Operation timeout is a top-level restriction that makes sure a blocking method will not be blocked more than this. In each operation, if rpc request fails because of timeout or other reason, it will retry until success or throw a RetriesExhaustedException. But if the total time being blocking reach the operation timeout before retries exhausted, it will break early and throw SocketTimeoutException.

参数:

operationTimeout - the total timeout of each operation in millisecond.

getOperationTimeout

int getOperationTimeout()

Get timeout (millisecond) of each operation for in Table instance.

getRpcTimeout

@Deprecated
int getRpcTimeout()

已过时。 Use getReadRpcTimeout or getWriteRpcTimeout instead

Get timeout (millisecond) of each rpc request in this Table instance.

setRpcTimeout

@Deprecated
void setRpcTimeout(int rpcTimeout)

已过时。 Use setReadRpcTimeout or setWriteRpcTimeout instead

Set timeout (millisecond) of each rpc request in operations of this Table instance, will override the value of hbase.rpc.timeout in configuration. If a rpc request waiting too long, it will stop waiting and send a new request to retry until retries exhausted or operation timeout reached.

NOTE: This will set both the read and write timeout settings to the provided value.

参数:

rpcTimeout - the timeout of each rpc request in millisecond.

getReadRpcTimeout

int getReadRpcTimeout()

Get timeout (millisecond) of each rpc read request in this Table instance.

setReadRpcTimeout

void setReadRpcTimeout(int readRpcTimeout)

Set timeout (millisecond) of each rpc read request in operations of this Table instance, will override the value of hbase.rpc.read.timeout in configuration. If a rpc read request waiting too long, it will stop waiting and send a new request to retry until retries exhausted or operation timeout reached.

参数:

readRpcTimeout -

getWriteRpcTimeout

int getWriteRpcTimeout()

Get timeout (millisecond) of each rpc write request in this Table instance.

setWriteRpcTimeout

void setWriteRpcTimeout(int writeRpcTimeout)

Set timeout (millisecond) of each rpc write request in operations of this Table instance, will override the value of hbase.rpc.write.timeout in configuration. If a rpc write request waiting too long, it will stop waiting and send a new request to retry until retries exhausted or operation timeout reached.

参数:
