batch
default void batch(List<? extends Row> actions, Object[] results) throws IOException, InterruptedException 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 samebatch(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.- Parameters:
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.

Delete
will report as though sucessful delete; no exception will be thrown. If there are any failures even after retries, aRetriesExhaustedWithDetailsException
will be thrown. RetriesExhaustedWithDetailsException contains lists of failedDelete
s and corresponding remote exceptions.- Parameters:
deletes
- List of things to delete. The input list gets modified by this method. All successfully appliedDelete
s in the list are removed (in particular it gets re-ordered, so the order in which the elements are inserted in the list gives no guarantee as to the order in which theDelete

method will be called with the return value from each region's invocation.- Type Parameters:
R
- the response type for the coprocessor Service method- Parameters:
methodDescriptor
- the descriptor for the protobuf service method to call.request
- the method call parametersstartKey
- start region selection with region containing this row. Ifnull
, the selection will start with the first table region.endKey
- select regions up to and including the region containing this row. Ifnull
, selection will continue through the last table region.responsePrototype
- the proto type of the response of the method in Service.callback
- callback to invoke with the response for each region- Throws:

checkAndMutate
@Deprecated default boolean checkAndMutate(byte[] row, byte[] family, byte[] qualifier, CompareFilter.CompareOp compareOp, byte[] value, RowMutations mutation) throws IOException Deprecated.Since 2.0.0. Will be removed in 3.0.0. UsecheckAndMutate(byte[], byte[])
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) The expected value argument of this call is on the left and the current value of the cell is on the right side of the comparison operator. Ie. eg. GREATER operator means expected value > existing <=> perform row mutations.- Parameters:
row
- to checkfamily
- column family to checkqualifier
- column qualifier to checkcompareOp
- the comparison operatorvalue
- the expected valuemutation
- mutations to perform if check succeeds- Returns:
- true if the new put was executed, false otherwise
- Throws:
IOException

getRpcTimeout
Get timeout of each rpc request in this Table instance. It will be overridden by a more specific rpc timeout config such as readRpcTimeout or writeRpcTimeout.- Parameters:
unit
- the unit of time the timeout to be represented in- Returns:
- rpc timeout in the specified time unit
- See Also:
-
getRpcTimeout
Deprecated.usegetReadRpcTimeout(TimeUnit)
orgetWriteRpcTimeout(TimeUnit)
insteadGet timeout (millisecond) of each rpc request in this Table instance.- Returns:
- Currently configured read timeout
-
setRpcTimeout
Deprecated.Use setReadRpcTimeout or setWriteRpcTimeout insteadSet 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.
- Parameters:
rpcTimeout
- the timeout of each rpc request in millisecond.
-
getReadRpcTimeout
Get timeout of each rpc read request in this Table instance.- Parameters:
unit
- the unit of time the timeout to be represented in- Returns:
- read rpc timeout in the specified time unit
-
getReadRpcTimeout

insteadGet timeout (millisecond) of each rpc read request in this Table instance. -
setReadRpcTimeout
Deprecated.since 2.0.0, useTableBuilder.setReadRpcTimeout(int)
insteadSet 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.- Parameters:
readRpcTimeout
- the timeout for read rpc request in milliseconds
-
getWriteRpcTimeout
Get timeout of each rpc write request in this Table instance.- Parameters:
unit
- the unit of time the timeout to be represented in- Returns:
- write rpc timeout in the specified time unit
-
getWriteRpcTimeout
Deprecated.since 2.0 and will be removed in 3.0 version usegetWriteRpcTimeout(TimeUnit)
insteadGet timeout (millisecond) of each rpc write request in this Table instance. -
setWriteRpcTimeout
Deprecated.since 2.0.0, useTableBuilder.setWriteRpcTimeout(int)
insteadSet 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.- Parameters:
writeRpcTimeout
- the timeout for write rpc request in milliseconds
-
getOperationTimeout
Get timeout of each operation in Table instance.- Parameters:
unit
- the unit of time the timeout to be represented in- Returns:
- operation rpc timeout in the specified time unit
-
getOperationTimeout
Deprecated.since 2.0 and will be removed in 3.0 version usegetOperationTimeout(TimeUnit)
insteadGet timeout (millisecond) of each operation for in Table instance. -
setOperationTimeout
Deprecated.since 2.0.0, useTableBuilder.setOperationTimeout(int)
insteadSet 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.- Parameters:
operationTimeout
- the total timeout of each operation in millisecond.
