Ted Yu commented on HBASE-3255:
-------------------------------
I use the following code in Export.createSubmittableJob():
{code}
if (args.length > 5) {
// to select rows that match regex, such as "pkgindex.+"
Filter f = new RowFilter(CompareOp.EQUAL,
new RegexStringComparator(args[5]));
s.setFilter(f);
}
{code}
> Allow Export tool to choose subset of rows

> Project: HBase
> Issue Type: Improvement
> Components: util
> Affects Versions: 0.20.6
> Reporter: Ted Yu
>
> org.apache.hadoop.hbase.mapreduce.Export should allow user to specify a
> subset of rows.
> This capability would help develop solution for problem which produces
> unwanted rows (in .META. table e.g.) that must be deleted.
> One such case is https://issues.apache.org/jira/browse/HBASE-3251
> We can export the dangling row(s) from .META., delete it and later import the
> row(s) to (another) hbase instance.
