Key: MAPREDUCE-6038
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6038
Project: Hadoop Map/Reduce
Issue Type: Bug
Environment: java version 1.8.0_11 hostspot 64-bit
Reporter: Pei Ma
Assignee: Tsuyoshi Ozawa
Priority: Minor
Labels: BB2015-05-TBR
Fix For: 2.8.0
Attachments: MAPREDUCE-6038.1.patch, MAPREDUCE-6038.2.patch
As a beginner, when I learned about the basic of the mr, I found that I
cound't run the WordCount2 using the command bin/hadoop jar wc.jar
WordCount2 /user/joe/wordcount/input /user/joe/wordcount/output in the
Tutorial. The VM throwed the NullPoniterException at the line 47. In the line
45, the returned default value of conf.getBoolean is true. That is to say
when wordcount.skip.patterns is not set ,the WordCount2 will continue to
execute getCacheFiles.. Then patternsURIs gets the null value. When the
-skip option dosen't exist, wordcount.skip.patterns will not be set.
Then a NullPointerException come out.
At all, the block after the if-statement in line no. 45 shoudn't be executed
when the -skip option dosen't exist in command. Maybe the line 45 should
like that if (conf.getBoolean(wordcount.skip.patterns, false)) {
.Just change the boolean.
