morningman commented on issue #549: Add a colocate join meta repair tool
URL: https://github.com/apache/incubator-doris/issues/549#issuecomment-455062272
 
 
   There is a serious problem that if the metadata has error, the Frontend 
instance may not even able to start, so that both HTTP or SQL way is useless...
   
   In your case, you may be able to start the FE and fix the bug using some 
tools. So it is OK to develop a specified tool to fit your situation. But for a 
common 'metadata fix tools', we should consider more.
   
   And also, we currently don't have a framework to redirect the request from 
non-master FE to Master FE(which SQL has), so you need to send the request 
directly to the Master FE, which may not be able to do so in some environment, 
such as visiting a proxy with 3 Frontends under it. You need also think about 
it.
