Description

Rsgroup.jsp calls Admin#listTableDescriptors((Pattern)null, true) with Pattern null but implementation RawAsyncHBaseAdmin#listTableDescriptors don't allow null by Precondition. Also, the suggestion listTables(boolean) is removed/deprecated already.

 

HTTP ERROR 500
Problem accessing /rsgroup.jsp. Reason:    
Server Error
Caused by:java.lang.NullPointerException: pattern is null. If you don't specify a pattern, use listTables(boolean) instead
