List of blockReport() Examples

Examples of blockReport()

org.apache.hadoop.hdfs.server.datanode.DataNode.BPOfferService.blockReport()
org.apache.hadoop.hdfs.server.namenode.NameNode.blockReport()
org.apache.hadoop.hdfs.server.protocol.DatanodeProtocol.blockReport()
blockReport() tells the NameNode about all the locally-stored blocks. The NameNode returns an array of Blocks that have become obsolete and should be deleted. This function is meant to upload *all the locally-stored blocks. It's invoked upon startup and then infrequently afterwards. @param registration @param blocks - the block list as an array of longs.Each block is represented as 2 longs. This is done instead of Block[] to reduce memory used by block reports. @return - the next command for DN to process. @throws IOException
