There is a utility in hive which can validate/fix corrupted

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.
