Description

It is desirable to add record filtering capability to HBase Export.

The following code is an example (s is the Scan):
byte [] prefix = Bytes.toBytes(args[5]);
if (args[5].startsWith("^"))

{ s.setFilter(new RowFilter(CompareOp.EQUAL, new RegexStringComparator(args[5]))); }

else s.setFilter(new PrefixFilter(prefix));
