Cluster: A cluster in Hadoop is used for distirbuted computing, where it can store and analyze huge amount structured and unstructured data. A common Hadoop cluster architecture consists of a two-level network topology, as illustrated in Figure Typically there are 30 to 40 servers per rack, with a 1 GB switch for the rack (only three are shown in the diagram), and an uplink to a core switch or router (which is normally 1 GB or better). %�쏢 �2z���/�~{�ݟ.o�|B*!�'���~o�;d*�S�j��\uNi߾�oHY��Jo�,#V.O�#�:T�W�J,�{�%��#���G�w���٦c�8�}�f�R�����"�����7p�#�ܯN���6!�`g��K�?��[�ꉵ���É>�j^�/�{�}���/s*f�O!�N#����Ә�n�C��(e��Y�m�̏������E�.
