hadoop wordcount 예제 eclilpse maven build 시 발생하는 오류
우선 maven build 전 maven clean을 해주셔야 합니다.

그리고 maven build를 했지만 아래와 같은 에러를 만났습니다.

You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>.

pom.xml에
build에 <defaultGoal>install</defaultGoal> 추가
<build>
<defaultGoal>install</defaultGoal>
</build>
이렇게 해주시면 됩니다.
<defaultGoal>은 아무것도 지정하지 않은 goal의 실행시 실행되는 목적 install, clean, package, build등을 정합니다.
