Example 13 with Options

use of org.apache.hbase.thirdparty.org.apache.commons.cli.Options in project hbase by apache.

the class RegionSplitter method main.

/**
 * The main function for the RegionSplitter application. Common uses:
 * <p>
 * <ul>
 * <li>create a table named 'myTable' with 60 pre-split regions containing 2
 * column families 'test' &amp; 'rs', assuming the keys are hex-encoded ASCII:
 * <ul>
 * <li>bin/hbase org.apache.hadoop.hbase.util.RegionSplitter -c 60 -f test:rs
 * myTable HexStringSplit
 * </ul>
 * <li>create a table named 'myTable' with 50 pre-split regions,
 * assuming the keys are decimal-encoded ASCII:
 * <ul>
 * <li>bin/hbase org.apache.hadoop.hbase.util.RegionSplitter -c 50
 * myTable DecimalStringSplit
 * </ul>
 * <li>perform a rolling split of 'myTable' (i.e. 60 =&gt; 120 regions), # 2
 * outstanding splits at a time, assuming keys are uniformly distributed
 * bytes:
 * <ul>
 * <li>bin/hbase org.apache.hadoop.hbase.util.RegionSplitter -r -o 2 myTable
 * UniformSplit
 * </ul>
 * </ul>
 *
 * There are three SplitAlgorithms built into RegionSplitter, HexStringSplit,
 * DecimalStringSplit, and UniformSplit. These are different strategies for
 * choosing region boundaries. See their source code for details.
 *
 * @param args
 *          Usage: RegionSplitter &lt;TABLE&gt; &lt;SPLITALGORITHM&gt;
 *          &lt;-c &lt;# regions&gt; -f &lt;family:family:...&gt; | -r
 *          [-o &lt;# outstanding splits&gt;]&gt;
 *          [-D &lt;conf.param=value&gt;]

 *           HBase IO problem
 * @throws InterruptedException
 *           user requested exit
 * @throws ParseException
