Hadoop Eclipse Plugin EP2

Immediately after the last part.

There is always a problem when using Eclipse to do mapreduce locally.

I go online to copy someone else's code, create a local input folder, run locally.

At the end, you can produce an output folder as indicated in the code, which should have a file running the result.

However, I have copied several code, and there is only one that can actually run and produce the results.

No one willingly accepted such an outcome.

So do I.

But what can I do?

I searched the Internet for some methods, in this way, the program runs the process of logging no output problems are resolved.

However, even though the type and location of the error are shown in the log, this is not useful for correcting errors.

Go for a spin and go back to the original point.

Who can not explain, in the end is not the fate of the arrangement.

Click the Debug button.

In abashed, look at the lines of code that are marked green in the transformation.

Staring at a string of lines that are read into a line.

Suddenly, it is no longer in line with the format of the string.

A string in a file that should not appear in this folder.

Should not be read into the characters, should not appear in the file.

Where do they come from, and how do they relate to the problems I have encountered?

Go to the file directory and view the file.

There are no files that should not appear, as if nothing had happened.

But I vaguely know that the graphical interface can not see the file, will be nowhere to hide in the command line.

Should not appear in the document, in the graphical interface is not visible, unexpectedly long a small tail "~" to live, can only be seen with the command line.

The data in them goes into the program running.

The format is not correct, the program will not run normally.

Delete them and run the program again.

Expect the result, it seems to be so beautiful.
