Get all column's qualifier that matches regex [closed]


Is it possible get all of the column qualifier's names with pattern matching? E.g. Get all column's qualifiers that starts with myNeeded_
Thank you.
Answer is Yes. Use ColumnPrefixFilter.
ColumnPrefixFilter columnPrefixFilter = new ColumnPrefixFilter(qualifierPrefix);
Scan scan = new Scan();
scan.setFilter(columnPrefixFilter);
There are more examples of ColumnPrefixFilter if interested.
