error @ after startminicluster() of work of instantiating environment, drop in between due above error. things tried:
- if roll hbasecdhversion 0.94.2-cdh4.2.0 version of 0.92.1-cdh4.x.x, works.
- removed .m2 cache , see 0.94.2-cdh4.2.0 created.
- tried versions of 0.94.2-cdh4.x.x
- i run mvn clean , install via commandline , not relying on eclipse magic, aslo tried eclipse:eclipse.
- check type/resource through eclipse missing class , points correct version of local repo, can find via eclipse.
- observe dependency tree conflicts.
- i opened repo jar myself , saw class exists.
- tried creating new project , create pom file scratch.
any pointers appreciated.
the problem commons-configuration jar. parent pom bringing in 1.9 version, leading conflicts hadoop common jar bringing in 1.6 version. way figure out problem keeping minmum dependency in parent pom , uncommenting dependencies 1 one narrow down problem. once problem found exclude dependencies in hadoop commons dependency. hope helps someone. hadoop jar should upgrade there commons-configuration 5 years old right now. can roll latest jar 1.9 1.6
