Answer 1

this was fixed in plasma 1.2.0 and is up on Maven Central. See Plasma Release 1.2.0 for details. I assume you are using cloudgraph.hbase or cloudgraph.rdb. If so you can just upgrade to CloudGraph 0.6.0 beta which depends on plasma 1.2.0. Note that some mapreduce classes under cloudgraph.hbase were promoted (moved up) in case you are using these. So then your pom.xml looks something like:

<dependency>
    <groupId>org.cloudgraph</groupId>
    <artifactId>cloudgraph-hbase</artifactId>
    <version>0.6.0</version>
</dependency>
