Eclipse Local Run MapReduce console print MapReduce execution progress

In the process of local mapreduce development, it was found that the Eclipse console could not print the progress of the MapReduce job I wanted to see and some parameters before guessing it might have been a log4j problem, and had indeed reported Log4j's warning, and then tried it, It's really a log4j problem.

Mainly because I did not configure Log4j.properties, the first new file in the SRC directory, and then add the following code:

Log4j.rootlogger=info, Stdoutlog4j.appender.stdout=org.apache.log4j.consoleappenderlog4j.appender.stdout.layout =org.apache.log4j.patternlayoutlog4j.appender.stdout.layout.conversionpattern=%d%p [%c]-%m% nlog4j.appender.logfile=org.apache.log4j.fileappenderlog4j.appender.logfile.file=target/ spring.loglog4j.appender.logfile.layout= org.apache.log4j.patternlayoutlog4j.appender.logfile.layout.conversionpattern=%d%p [%c]-%m%n

Run the program again, control print I want to see the MapReduce execution progress and related parameters, here for the moment do not introduce the details of log4j configuration, I will come up with a separate article to introduce the configuration of log4j
