      Controls the automatic adjustment of ranges for this job. This feature merges overlapping ranges, then splits them to align with tablet boundaries. Disabling this feature will cause exactly one Map task to be created for each specified range. The default setting is enabled. *

      Deprecated.
      since 1.6.0; Configure your job with the appropriate InputFormat or OutputFormat.
      Controls the use of the ClientSideIteratorScanner in this job.

    • setOfflineTableScan

      @Deprecated public static void setOfflineTableScan(Class<?> implementingClass, org.apache.hadoop.conf.Configuration conf, boolean enableFeature)
      Deprecated.
      since 1.6.0; Configure your job with the appropriate InputFormat or OutputFormat.
      Enable reading offline tables. By default, this feature is disabled and only online tables are scanned. This will make the map reduce job directly read the table's files. If the table is not offline, then the job will fail. If the table comes online during the map reduce job, it is likely that the job will fail.

      To use this option, the map reduce user will need access to read the Accumulo directory in HDFS.

      Reading the offline table will create the scan time iterator stack in the map process. So any iterators that are configured for the table will need to be on the mapper's classpath. The accumulo-site.xml may need to be on the mapper's classpath if HDFS or the Accumulo directory in HDFS are non-standard.

      One way to use this feature is to clone a table, take the clone offline, and use the clone as the input table for a map reduce job. If you plan to map reduce over the data many times, it may be better to the compact the table, clone it, take it offline, and use the clone for all map reduce jobs. The reason to do this is that compaction will reduce each tablet in the table to one file, and it is faster to read from one file.

      There are two possible advantages to reading a tables file directly out of HDFS. First, you may see better read performance. Second, it will support speculative execution better. When reading an online table speculative execution can put more load on an already slow tablet server.

      By default, this feature is disabled.

      Parameters:
      implementingClass - the class whose name will be used as a prefix for the property configuration key
      conf - the Hadoop configuration object to configure
