Hive Metastore Client. The public implementation of IMetaStoreClient. Methods not inherited from IMetaStoreClient are not public and can change. Hence this is marked as unstable. For users who require retry mechanism when the connection between metastore and client is broken, RetryingMetaStoreClient class should be used.

    dbName - database name.
    
    tblName - table name.
    
    partExprs - I don't understand this fully, so can't completely explain it. The second half of the object pair is an expression used to determine which partitions to drop. The first half has something to do with archive level, but I don't understand what. I'm also not sure what happens if you pass multiple expressions.
    
    deleteData - whether to delete the data as well as the metadata.
    
    ifExists - if true, it is not an error if no partitions match the expression(s).

    Get tables as objects (rather than just fetching their names). This is more expensive and should only be used if you actually need all the information about the tables.

    getTableObjectsByName in interface IMetaStoreClient
    
    Parameters:

    Returns:
    
    A list of objects representing the tables. Only the tables that can be retrieved from the database are returned. For example, if none of the requested tables could be retrieved, an empty list is returned. There is no guarantee of ordering of the returned tables.

    Get a list of table names that match a filter. The filter operators are LIKE, <, <=, >, >=, =, <> In the filter statement, values interpreted as strings must be enclosed in quotes, while values interpreted as integers should not be. Strings and integers are the only supported value types. The currently supported key names in the filter are: Constants.HIVE_FILTER_FIELD_OWNER, which filters on the tables' owner's name and supports all filter operators Constants.HIVE_FILTER_FIELD_LAST_ACCESS, which filters on the last access times and supports all filter operators except LIKE Constants.HIVE_FILTER_FIELD_PARAMS, which filters on the tables' parameter keys and values and only supports the filter operators = and <>. Append the parameter key name to HIVE_FILTER_FIELD_PARAMS in the filter statement. For example, to filter on parameter keys called "retention", the key name in the filter statement should be Constants.HIVE_FILTER_FIELD_PARAMS + "retention" Also, = and <> only work for keys that exist in the tables. E.g., filtering on tables where key1 <> value will only return tables that have a value for the parameter key1.

```
    Description copied from interface: IMetaStoreClient
    
    Initiate a batch of transactions. It is not guaranteed that the requested number of transactions will be instantiated. The system has a maximum number instantiated per request, controlled by hive.txn.max .batch.open in hive-site.xml. If the user requests more than this value, only the configured max will be returned.
    Increasing the number of transactions requested in the batch will allow applications that stream data into Hive to place more commits in a single file, thus reducing load on the namenode and making reads of the data more efficient. However, opening more transactions in a batch will also result in readers needing to keep a larger list of open transactions to ignore, potentially slowing their reads. Users will need to test in their system to understand the optimal number of transactions to request in a batch.
    
    Specified by:
    
    openTxns in interface IMetaStoreClient
    
    Parameters:
    
    user - User who is opening this transaction. This is the Hive user, not necessarily the OS user. It is assumed that this user has already been authenticated and authorized at this point.
    
    numTxns - number of requested transactions to open
    
    Returns:
    
    list of opened txn ids. As noted above, this may be less than requested, so the user should check how many were returned rather than optimistically assuming that the result matches the request.

    Request a set of locks. All locks needed for a particular query, DML, or DDL operation should be batched together and requested in one lock call. This avoids deadlocks. It also avoids blocking other users who only require some of the locks required by this user.
    If the operation requires a transaction (INSERT, UPDATE, or DELETE) that transaction id must be provided as part this lock request. All locks associated with a transaction will be released when that transaction is committed or rolled back.
    *
    Once a lock is acquired, IMetaStoreClient.heartbeat(long, long) must be called on a regular basis to avoid the lock being timed out by the system.

    Parameters:
    
    request - The lock request. LockRequestBuilder can be used construct this request.
    
    Returns:
    
    a lock response, which will provide two things, the id of the lock (to be used in all further calls regarding this lock) as well as a state of the lock. If the state is ACQUIRED then the user can proceed. If it is WAITING the user should wait and call IMetaStoreClient.checkLock(long) before proceeding. All components of the lock will have the same state.

    lockid - the id of the locks obtained. If no locks have been obtained then this can be set to 0.
    
    Throws:
