> Some tools print bin/hbase in their usage documentation.{{bin/hbase}} is only applicable to development environments. Typical deployments always should  just refer to {{hbase}}. 
> For example, CopyTable usage is like: 
> {code}
> Usage: CopyTable [general options] [--starttime=X] [--endtime=Y] [--new.name=NEW] [--peer.adr=ADR] <tablename>
> Options:
>  rs.class     hbase.regionserver.class of the peer cluster
>               specify if different from current cluster
>  rs.impl      hbase.regionserver.impl of the peer cluster
>  startrow     the start row
>  stoprow      the stop row
>  starttime    beginning of the time range (unixtime in millis)
>               without endtime means from starttime to forever
>  endtime      end of the time range.  Ignored if no starttime specified.
>  versions     number of cell versions to copy
>  new.name     new table's name
>  peer.adr     Address of the peer cluster given in the format
>               hbase.zookeeper.quorum:hbase.zookeeper.client.port:zookeeper.znode.parent
>  families     comma-separated list of families to copy
>               To copy from cf1 to cf2, give sourceCfName:destCfName. 
>               To keep the same name, just give "cfName"
>  all.cells    also copy delete markers and deleted cells
>  bulkload     Write input into HFiles and bulk load to the destination table
> Args:
>  tablename    Name of the table to copy
> Examples:
>  To copy 'TestTable' to a cluster that uses replication for a 1 hour window:
>  $ bin/hbase org.apache.hadoop.hbase.mapreduce.CopyTable --starttime=1265875194289 --endtime=1265878794289 --peer.adr=server1,server2,server3:2181:/hbase --families=myOldCf:myNewCf,cf2,cf3 TestTable 
> For performance consider the following general option:
>   It is recommended that you set the following to >=100. A higher value uses more memory but
>   decreases the round trip time to the server and may increase performance.
>     -Dhbase.client.scanner.caching=100
>   The following should always be set to false, to prevent writing data twice, which may produce 
>   inaccurate results.
>     -Dmapreduce.map.speculative=false
> {code}
> in above, it should be: 
> {code}
>  To copy 'TestTable' to a cluster that uses replication for a 1 hour window:
>  $ hbase org.apache.hadoop.hbase.mapreduce.CopyTable --starttime=1265875194289 --endtime=1265878794289 --peer.adr=server1,server2,server3:2181:/hbase --
> families=myOldCf:myNewCf,cf2,cf3 TestTable 
> {code}
