private boolean setWriteIdForAcidDdl() throws SemanticException, LockException {
    DDLDescWithWriteId acidDdlDesc = driverContext.getPlan().getAcidDdlDesc();
    boolean hasAcidDdl = acidDdlDesc != null && acidDdlDesc.mayNeedWriteId();
    if (hasAcidDdl) {
        String fqTableName = acidDdlDesc.getFullTableName();
        TableName tableName = HiveTableName.of(fqTableName);
        long writeId = driverContext.getTxnManager().getTableWriteId(tableName.getDb(), tableName.getTable());
