-----------------------------------
+[~mohitsabharwal] - FYI
> Hive Metastore should use repeatable-read consistency level
> -----------------------------------------------------------
>
> Key: HIVE-14907
> URL: https://issues.apache.org/jira/browse/HIVE-14907
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 2.2.0
> Reporter: Lenni Kuff
>
> Currently HMS uses the "read-committed" consistency level which is the
> default for DataNucleus. This could cause potential problems since the state
> visible to each transaction can actually see updates from other transactions,
> so it is very difficult to reason about any code that reads multiple pieces
> of data.
> Instead it should use "repeatable-read" consistency which guarantees that any
> transaction only sees the state at the beginning of a transaction plus any
> updates done within a transaction.
