Description

For tables that use column encoding when we add a column to a view we need to update the encoded column qualifier counter on the base table. Currently we do this in two rpcs:

                    // there should only be remote mutations if we are creating a view that uses
                    // encoded column qualifiers (the remote mutations are to update the encoded
                    // column qualifier counter on the parent table)
                    if (parentTable != null && tableType == PTableType.VIEW && parentTable
                            .getEncodingScheme() != QualifierEncodingScheme.NON_ENCODED_QUALIFIERS) {
                        response =
                                processRemoteRegionMutations(
                                    PhoenixDatabaseMetaData.SYSTEM_CATALOG_NAME_BYTES,
                                    remoteMutations, MetaDataProtos.MutationCode.UNABLE_TO_UPDATE_PARENT_TABLE);
                        clearParentTableFromCache(clientTimeStamp,
                            parentTable.getSchemaName() != null
                                    ? parentTable.getSchemaName().getBytes()
                                    : ByteUtil.EMPTY_BYTE_ARRAY,
                            parentTable.getName().getBytes());
                        if (response != null) {
                            done.run(response);
                            return;
                        }
                    }
