> We use a tag of cell to indicat that some properties should not be derived from the base table for view table. VIEW_MODIFIED_PROPERTY_BYTES is used a tag bytes, but the format is incorrect, the below is a reference from KeyValue interface:
> {quote}KeyValue can optionally contain Tags. When it contains tags, it is added in the byte array after
>  * the value part. The format for this part is: <code><tagslength><tagsbytes></code>.
>  * <code>tagslength</code> maximum is <code>Short.MAX_SIZE</code>. The <code>tagsbytes</code>
>  * contain one or more tags where as each tag is of the form
>  * <code><taglength><tagtype><tagbytes></code>. <code>tagtype</code> is one byte
>  * and <code>taglength</code> maximum is <code>Short.MAX_SIZE</code> and it includes 1 byte type
>  * length and actual tag bytes length.{quote}
> The CATALOG table will be badly affected. Some errors will be caused when reads CATALOG table.
