             Summary: Handle missing hive.acid.key.index in the fixacidkeyindex utility
                 Key: HIVE-26146
                 URL: https://issues.apache.org/jira/browse/HIVE-26146
             Project: Hive
          Issue Type: Improvement
          Components: ORC, Transactions
    Affects Versions: 4.0.0-alpha-2
            Reporter: Alessandro Solimando
            Assignee: Alessandro Solimando


There is a utility in hive which can validate/fix corrupted _hive.acid.key.index_: 

{code:bash}
hive --service fixacidkeyindex
{code}

At the moment the utility throws a NPE if the _hive.acid.key.index_ metadata entry is missing:

The aim of this ticket is to handle such case in order to support re-generating this metadata entry even when it is missing.
