Chia-Ping Tsai commented on HBASE-20853:
----------------------------------------
{quote}but why does your code increment the value of a cell? It seems to be a
checkAndDelete.

Pardon me. I can't recall the comment because of bad memory. :(
What I want to to for Table#incrementColumnValue is shown below.
{code:java}
- default long incrementColumnValue(byte[] row, byte[] family, byte[]
qualifier, long amount)
- throws IOException {
- throw new NotImplementedException("Add an implementation!");
+ default long incrementColumnValue(byte[] row, byte[] family, byte[]
qualifier, long amount) throws IOException {
+ Cell cell = increment(new Increment(row).addColumn(family, qualifier,
amount)).getColumnLatestCell(family, qualifier);
+ return Bytes.toLong(cell.getValueArray(), cell.getValueOffset(),
cell.getValueLength());
{code}
