createBatchScanner

public BatchScanner createBatchScanner(String tableName,
                                       Authorizations authorizations,
                                       int numQueryThreads)

Description copied from class: Connector
Factory method to create a BatchScanner connected to Accumulo.

Specified by:
createBatchScanner in class Connector
Parameters:
tableName - the name of the table to query
authorizations - A set of authorization labels that will be checked against the column visibility of each key in order to filter data. The authorizations passed in must be a subset of the accumulo user's set of authorizations. If the accumulo user has authorizations (A1, A2) and authorizations (A2, A3) are passed, then an exception will be thrown.
numQueryThreads - the number of concurrent threads to spawn for querying
Returns:
BatchScanner object for configuring and querying
Throws:
TableNotFoundException - when the specified table doesn't exist
