{code}

the following command will work with uri
{code}
hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot snapshotT1_dn -copy-to hdfs://hdtest014.svl.ibm.com:9000/user/demai/backup2
{code}

The bug is the same as [Hadoop-9069|https://issues.apache.org/jira/browse/HADOOP-9069]. Since the hadoop jira has been sitting there for more than a year, use this jira for a local hbase fix for now. 

Many thanks for [~mbertozzi] help on this one.
