Re: Some mappers are much slower than others in reading data from HDFS

Your output shows that node2 has 13 mappers and the reducer, while node3 and node4 had only 8 mappers each. So I'd expect some disparity. Since it's hard to correlate the mapper throughput against the reducer throughput, it's possible that node3 got just as much work done. That doesn't explain wh

Re: Why the official Hadoop Documents are so messy?

Hi, I am not sure if your complaint is as much about the changing interfaces as it is about documentation. Please note that versions prior to 1.0 did not have stable interfaces as a major requirement. Not by choice, but because the focus was on seemingly more important functionality, stability, p

Re: new to hadoop and first question

Re: Why the official Hadoop Documents are so messy?

Hello there, Thank you for the comments. But, just to let you know, it's a community work and no one in particular can be held responsible for these kind of small things. This is how open source works. Guys who are working on Hadoop have a lot of things to do. In spite of that, they are givin
