Subject help me answer some questions about HDFS
Date Wed, 31 Aug 2011 07:13:36 GMT

Nice to me you!


I am a beginner of hadoop,and when I study about the utility of hadoop.I
find that there is only one namenode which is key to the whole system. Hdfs
provides a auxiliary namenode which is helpful when the namenode crashes,but
this process maybe waste a lot of time .What I am trying to say is that can
we design the hdfs to the multi-master mode with no single points of failure
or such as dual-system hot backup. This is just my guession when studying
the hadoop.


Thanks for your early reply.


Best Regards,
