HangyuanLiu opened a new pull request #1921: Remove length equal restrict in schema change
URL: https://github.com/apache/incubator-doris/pull/1921
 
 
   #1920 
   
   I found out that it was the length after schema change must be greater than or equal to the length before schema change. But "=" is unnecessary and restricts other normal operations, such as converting non-null types to nullable types without modifying the character length.
   
   And If the user sends a schema change request of the same length, the operation of schema chang is not performed.  Doris can throw exception "ERROR 1064 (HY000): Nothing is changed. please check your alter stmt."
