> HBase should run on both secure and vanilla versions of Hadoop 0.20

> Key: HBASE-3194
> URL: https://issues.apache.org/jira/browse/HBASE-3194
> Project: HBase
> Issue Type: Bug
> Reporter: Gary Helmling
> Assignee: stack
> Fix For: 0.90.0
>
>
> There have been a couple cases recently of folks trying to run HBase trunk
> (or 0.89 DRs) on CDH3b3 or secure Hadoop. While HBase security is in the
> works, it currently only runs on secure Hadoop versions. Meanwhile HBase
> trunk won't compile on secure Hadoop due to backward incompatible changes in
> org.apache.hadoop.security.UserGroupInformation.
> This issue is to work out the minimal set of changes necessary to allow HBase
> to build and run on both secure and non-secure versions of Hadoop. Though,
> with secure Hadoop, I don't even think it's important to target running with
> HDFS security enabled (and krb authentication). Just allow HBase to build
> and run in both versions.
> I think mainly this amounts to abstracting usage of UserGroupInformation and
> UnixUserGroupInformation.
