Ayappan commented on HADOOP-11790:

Switching to RocksDB is really a good thing to do. It's a very active one 
unlike leveldb. The latest released ones 5.4.7 & 5.5.1 has PowerPC support (fat 
jar in maven central repo has Power native library). 

> leveldb usage should be disabled by default or smarter about platforms

>                 URL: https://issues.apache.org/jira/browse/HADOOP-11790
>             Project: Hadoop Common
>          Issue Type: Bug
>    Affects Versions: 2.6.0, 3.0.0-alpha3
>         Environment: * any non-x86
> * any OS that isn't Linux, OSX, Windows
>            Reporter: Ayappan
>            Priority: Blocker
> The leveldbjni artifact in maven repository has been built for only x86 
> architecture. Due to which some of the testcases are failing in PowerPC. The 
> leveldbjni community has no plans to support other platforms [ 
> https://github.com/fusesource/leveldbjni/issues/54 ]. Right now , the 
> approach is we need to locally built leveldbjni prior to running hadoop 
> testcases. Pushing a PowerPC-specific leveldbjni artifact in central maven 
> repository and making pom.xml to pickup it up while running in PowerPC is 
> another option but i don't know whether this is a suitable one . Any other 
> alternative/solution is there ?
