Review Comment:
   I'm looking to log something like this 
   ```Column vector: 
org.apache.orc.storage.ql.exec.vector.BytesColumnVector@6a4c0a7f, resizing to: 
257610, child count: 25761``` where I need both the identityHash and the 
referring class name.
   
   I can look into the Util class. Can u point me to it? But IMO might be an 
overkill in replacing `cv`  to `GobblinUtil.hash(cv)` , no?
