Subject [jira] [Created] (HBASE-6834) HBaseClusterManager shell code breaks hadoop-2.0 build

-------------------------------------

             Summary: HBaseClusterManager shell code breaks hadoop-2.0 build
                 Key: HBASE-6834
                 URL: https://issues.apache.org/jira/browse/HBASE-6834
             Project: HBase
          Issue Type: Bug
            Reporter: Gregory Chanan


I get the following error:
{noformat}
HBaseClusterManager.java:[73,23] getExecString() in org.apache.hadoop.hbase.HBaseClusterManager.RemoteShell
cannot override getExecString() in org.apache.hadoop.util.Shell.ShellCommandExecutor; attempting
to assign weaker access privileges; was public
{noformat}

the issue is that getExecString() is declared public in hadoop-2.0, but protected in hadoop-1.0.
 In HBase, it is declared protected, and you can't downgrade from public to protected.

We can just declare the function public and that seems to work, but given that in hadoop the
class is declared
{code}
@InterfaceAudience.LimitedPrivate({"HDFS", "MapReduce"})
{code}
perhaps we should just copy the class into hbase source.
