Description

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.

alter 'test_table', CONFIGURATION => {'hbase.rs.cachecompactedblocksonwrite.threshold' => ''}
