    So here is where I am after reading through this.
    
    Replace the table with a paragraph that combines the wording from
    
    > Accumulo has been built and tested with specific dependency versions. Please check the release notes at https://accumulo.apache.org for the version of Accumulo you're using, for any known compatibility issues.
    
    and 
    
    > The versions set in the pom for Hadoop and ZooKeeper are treated as stable releases which provide a large-breadth of compatibility across other versions of those components. They do not guarantee compatibility with any other versions because Hadoop and ZooKeeper do not provide any such guarantee.
    
    and include a warning about getting the thrift version correct.
