Class AbstractInputFormat<K,​V>

  • All Implemented Interfaces:
    org.apache.hadoop.mapred.InputFormat<K,​V>
    Direct Known Subclasses:
    AccumuloMultiTableInputFormat, InputFormatBase
    @Deprecated(since="2.0.0")
public abstract class AbstractInputFormat<K,​V>
extends Object
implements org.apache.hadoop.mapred.InputFormat<K,​V>
    Deprecated.
    since 2.0.0; Use org.apache.accumulo.hadoop.mapred instead from the accumulo-hadoop-mapreduce.jar
    An abstract input format to provide shared methods common to all other input format classes. At the very least, any classes inheriting from this class will need to define their own RecordReader.

      • 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)
        token - the user's password
        Throws:
        AccumuloSecurityException
        Since:
        1.5.0

      • setConnectorInfo

                                    String tokenFile)
                             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)
        tokenFile - the path to the token file
