-------------------------------------------------
Thanks for the patch Dumindu.
{code}
indexKVs.add(new KeyValueColumnExpression(expression.getColumn()));
648 children.set(0, new
KeyValueColumnExpression(expression.getColumn()));
{code}
Two KeyValueColumnExpression objects need not be created. Create one and use it.
{code}
//Find the Cell with exact value of array index
{code}
This part why is it having other cells other than the special KV that gives the
given array index.
Because in the server we have removed the other cells and create a result with
the dummy KV.
See BaseScannerRegionObserver in
{code}
result.add(new KeyValue(rowKv.getRowArray(),
rowKv.getRowOffset(), rowKv.getRowLength(),
QueryConstants.ARRAY_VALUE_COLUMN_FAMILY, 0,
QueryConstants.ARRAY_VALUE_COLUMN_FAMILY.length,
QueryConstants.ARRAY_VALUE_COLUMN_QUALIFIER, 0,
QueryConstants.ARRAY_VALUE_COLUMN_QUALIFIER.length,
HConstants.LATEST_TIMESTAMP,
Type.codeToType(rowKv.getTypeByte()), value, 0,
value.length));
{code}
