      • setConnectorInfo

        public static void setConnectorInfo​(org.apache.hadoop.mapred.JobConf job,
                                    String principal,
                                    AuthenticationToken token)
                             throws AccumuloSecurityException
        Deprecated.
        Sets the connector information needed to communicate with Accumulo in this job.

        WARNING: Some tokens, when serialized, divulge sensitive information in the configuration as a means to pass the token to MapReduce tasks. This information is BASE64 encoded to provide a charset safe conversion to a string, but this conversion is not intended to be secure. PasswordToken is one example that is insecure in this way; however DelegationTokens, acquired using SecurityOperations.getDelegationToken(DelegationTokenConfig), is not subject to this concern.

        Parameters:
        job - the Hadoop job instance to be configured
        principal - a valid Accumulo user name (user must have Table.CREATE permission if setCreateTables(JobConf, boolean) is set to true)
        token - the user's password
        Throws:
        AccumuloSecurityException
        Since:
        1.5.0

      • setConnectorInfo

                             throws AccumuloSecurityException
        Deprecated.
        Sets the connector information needed to communicate with Accumulo in this job.

        Stores the password in a file in HDFS and pulls that into the Distributed Cache in an attempt to be more secure than storing it in the Configuration.

        Parameters:
        job - the Hadoop job instance to be configured
        principal - a valid Accumulo user name (user must have Table.CREATE permission if setCreateTables(JobConf, boolean) is set to true)
        tokenFile - the path to the password file
        Throws:
        AccumuloSecurityException
