> Currently we filter out the parent table columns while creating a view. If we
> have to support rollback we still need to write the parent table column
> metadata.
> Instead of this we should filter out the duplicate columns in
> {{MetaDataEndpointImpl.combineColumns}}
> {code}
> // Here we are passed the parent's columns to add to a view, PHOENIX-3534
> allows for a splittable
> // System.Catalog thus we only store the columns that are new to
> the view, not the parents columns,
> // thus here we remove everything that is ORDINAL.POSITION <=
> baseColumnCount and update the
> // ORDINAL.POSITIONS to be shifted accordingly.
> // TODO PHOENIX-4767 remove the following code that removes the
> base table column metadata in the next release
> if (PTableType.VIEW.equals(tableType) &&
> !ViewType.MAPPED.equals(viewType)) {
> boolean isSalted = MetaDataUtil.getSaltBuckets(tableMetadata,
> GenericKeyValueBuilder.INSTANCE, new ImmutableBytesWritable()) > 0;
> int baseColumnCount =
> MetaDataUtil.getBaseColumnCount(tableMetadata) - (isSalted ? 1 : 0);
> if (baseColumnCount > 0) {
> Iterator<Mutation> mutationIterator =
> tableMetadata.iterator();
> while (mutationIterator.hasNext()) {
> Mutation mutation = mutationIterator.next();
> // if not null and ordinal position < base column
> count remove this mutation
> ImmutableBytesWritable ptr = new
> ImmutableBytesWritable();
> MetaDataUtil.getMutationValue(mutation,
