> 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.
