Examples with KillQueryImpl org.apache.hive.service.server.KillQueryImpl used on opensource projects

Example 1 with KillQueryImpl

use of org.apache.hive.service.server.KillQueryImpl in project hive by apache.

the class HiveSessionImpl method open.

@Override
public /**
 * Opens a new HiveServer2 session for the client connection.
 * Creates a new SessionState object that will be associated with this HiveServer2 session.
 * When the server executes multiple queries in the same session,
 * this SessionState object is reused across multiple queries.
 * Note that if doAs is true, this call goes through a proxy object,
 * which wraps the method logic in a UserGroupInformation#doAs.
 * That's why it is important to create SessionState here rather than in the constructor.
