> If the metadata of the table is set to null, the metadata will be removed.
> The code is:
> [https://github.com/apache/hbase/blob/b07549febb462b072792659051c64bb54d122771/hbase-client/src/main/java/org/apache/hadoop/hbase/client/TableDescriptorBuilder.java#L721]
> But if set metadata as empty string, serious errors may occur. Some metadata
> is number,
> it will throw a NumberFormatException when converting empty string to a
> number. If the exception is thrown when the region is initialized, all
> regions of the table will be in RIT.
> The following command can reproduced this issue. *Note: Please execute in the
> test environment.*
> {code:java}
> alter 'test_table', CONFIGURATION =>
> {'hbase.rs.cachecompactedblocksonwrite.threshold' => ''}
> {code}
