morningman opened a new issue #1885: Wrong distribution for random distribution 
table
URL: https://github.com/apache/incubator-doris/issues/1885
 
 
   **Describe the bug**
   Doris incorrectly use all columns(including value columns) as distribution 
columns of the table with random distribution in loading process.
   
   This cause a completely wrong data distribution for these table, and unable 
to correct.
   And even we can not fix this bug, because if we modify it, the new incoming 
data will be distributed to different tablet.
   
   So, the only way to fix it, is to rebuild the table and reloaded data into 
it.
   
   And we should also forbid converting random distribution to hash 
distribution if table has value columns.
