Uses of Job in org.apache.hadoop.mapreduce.lib.db

Methods in org.apache.hadoop.mapreduce.lib.db with parameters of type Job
`static void` | `DBInputFormat.setInput(Job job, Class<? extends DBWritable> inputClass, String inputQuery, String inputCountQuery)` Initializes the map-part of the job with the appropriate input settings.
`static void` | `DataDrivenDBInputFormat.setInput(Job job, Class<? extends DBWritable> inputClass, String inputQuery, String inputBoundingQuery)` setInput() takes a custom query and a separate "bounding query" to use instead of the custom "count query" used by DBInputFormat.
`static void` | `DBInputFormat.setInput(Job job, Class<? extends DBWritable> inputClass, String tableName, String conditions, String orderBy, String... fieldNames)` Initializes the map-part of the job with the appropriate input settings.
`static void` | `DataDrivenDBInputFormat.setInput(Job job, Class<? extends DBWritable> inputClass, String tableName, String conditions, String splitBy, String... fieldNames)` Note that the "orderBy" column is called the "splitBy" in this version.
`static void` | `DBOutputFormat.setOutput(Job job, String tableName, int fieldCount)` Initializes the reduce-part of the job with the appropriate output settings
`static void` | `DBOutputFormat.setOutput(Job job, String tableName, String... fieldNames)` Initializes the reduce-part of the job with the appropriate output settings

Uses of Job in org.apache.hadoop.mapreduce.lib.input

Methods in org.apache.hadoop.mapreduce.lib.input with parameters of type Job

`static void` | `FileInputFormat.addInputPaths(Job job, String commaSeparatedPaths)` Add the given comma separated paths to the list of inputs for the map-reduce job.
`static void` | `FileInputFormat.setInputPathFilter(Job job, Class<? extends PathFilter> filter)` Set a PathFilter to be applied to the input paths for the map-reduce job.
`static void` | `FileInputFormat.setInputPaths(Job job, Path... inputPaths)` Set the array of `Path`s as the list of inputs for the map-reduce job.
`static void` | `FileInputFormat.setInputPaths(Job job, String commaSeparatedPaths)` Sets the given comma separated paths as the list of inputs for the map-reduce job.
`static void` | `FileInputFormat.setMaxInputSplitSize(Job job, long size)` Set the maximum split size

`<K1,V1,K2,V2> void`
` | `MultithreadedMapper.setMapperClass(Job job, Class<? extends Mapper<K1,V1,K2,V2>> cls)` Set the application's mapper class.
`static void` | `MultithreadedMapper.setNumberOfThreads(Job job, int threads)` Set the number of threads in the pool for running maps.

Uses of Job in org.apache.hadoop.mapreduce.lib.output

Methods in org.apache.hadoop.mapreduce.lib.output with parameters of type Job
`static void` | `MultipleOutputs.addNamedOutput(Job job, String namedOutput, Class<? extends OutputFormat> outputFormatClass, Class<?> keyClass, Class<?> valueClass)` Adds a named output for the job.
`static void` | `FileOutputFormat.setCompressOutput(Job job, boolean compress)` Set whether the output of the job is compressed.
`static void` | `MultipleOutputs.setCountersEnabled(Job job, boolean enabled)` Enables or disables counters for the named outputs.
`static void` | `SequenceFileOutputFormat.setOutputCompressionType(Job job, SequenceFile.CompressionType style)` Set the `SequenceFile.CompressionType` for the output `SequenceFile`.
`static void` | `FileOutputFormat.setOutputCompressorClass(Job job, Class<? extends CompressionCodec> codecClass)` Set the `CompressionCodec` to be used to compress job outputs.
`static void` | `FileOutputFormat.setOutputPath(Job job, Path outputDir)` Set the `Path` of the output directory for the map-reduce job.
