List of addBlockAndFetchMetaInfo() Examples

Examples of addBlockAndFetchMetaInfo()

org.apache.hadoop.hdfs.protocol.ClientProtocol.addBlockAndFetchMetaInfo()
Return a block to the client that wants to write an additional block to the indicated filename (which must currently be open for writing). It also piggyback some cluster meta info, like protoccol version# and namespaceid. addBlock() allocates a new block and datanodes the block data should be replicated to. This method enables client compatibility which uses this method for adding blocks. @param excludedNodes a list of nodes that should not be allocated;implementation may ignore this @return LocatedBlock allocated block information and data transfer protocol version
