List of coprocessorProxy() Examples

Examples of coprocessorProxy()

org.apache.hadoop.hbase.client.HBaseAdmin.coprocessorProxy()
Creates and returns a proxy to the CoprocessorProtocol instance running in the master. @param protocol The class or interface defining the remote protocol @return A CoprocessorProtocol instance
org.apache.hadoop.hbase.client.HTable.coprocessorProxy()
{@inheritDoc}
org.apache.hadoop.hbase.client.HTableInterface.coprocessorProxy()
Creates and returns a proxy to the CoprocessorProtocol instance running in the 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 {@code row} parameter is also not passed to thecoprocessor handler registered for this protocol, unless the {@code row}is separately passed as an argument in a proxy method call. The parameter here is just used to locate the region used to handle the call. @param protocol The class or interface defining the remote protocol @param row The row key used to identify the remote region location @return A CoprocessorProtocol instance
