Aasha Medhi commented on HIVE-24032:
------------------------------------

Shims dependency is removed from the standalone-metastore module. [~vihangk1] 
had done some work to make the standalone-metastore indepdent and impala also 
uses this. We had to add shims dependencies for one of the replication related 
changes. We have reverted that now with this patch. Please note this is only 
for standalone-metastore module.

Also shims were introduced to support multiple hadoop versions but as of now we 
just support one. Even with ozone the FS apis can be used directly. So that was 
another reason for not introducing shims in standalone-metastore.
