<title>CopyTable</title>
<para>
CopyTable is a utility that can copy part or of all of a table, either to the same cluster or another cluster. The usage is as follows:
<programlisting>$ bin/hbase org.apache.hadoop.hbase.mapreduce.CopyTable [--rs.class=CLASS] [--rs.impl=IMPL] [--starttime=X] [--endtime=Y] [--new.name=NEW] [--peer.adr=ADR] tablename
<programlisting>$ bin/hbase org.apache.hadoop.hbase.mapreduce.CopyTable [--starttime=X] [--endtime=Y] [--new.name=NEW] [--peer.adr=ADR] tablename
</programlisting>
</para>
<para>
Options:
<itemizedlist>
<listitem><varname>rs.class</varname> hbase.regionserver.class of the peer cluster. Specify if different from current cluster.</listitem>
<listitem><varname>rs.impl</varname> hbase.regionserver.impl of the peer cluster. </listitem>
<listitem><varname>starttime</varname> Beginning of the time range. Without endtime means starttime to forever.</listitem>
<listitem><varname>endtime</varname> End of the time range. Without endtime means starttime to forever.</listitem>
<listitem><varname>versions</varname> Number of cell versions to copy.</listitem>
