<p>This command invokes the <em>Anonymizer</em> utility of
<em>Rumen</em>. It anonymizes sensitive information from the
<code>&lt;jobtrace-input&gt;</code> file and outputs the anonymized
content into the <code>&lt;jobtrace-output&gt;</code>
file. It also anonymizes the cluster layout (topology) from the
<code>&lt;topology-input&gt;</code> and outputs it in
the <code>&lt;topology-output&gt;</code> file.
<code>&lt;job-input&gt;</code> represents the job trace file obtained
using <code>TraceBuilder</code> or <code>Folder</code>.
<code>&lt;topology-input&gt;</code> represents the cluster topology
file obtained using <code>TraceBuilder</code>.

<title><em>Anonymizer</em> Configuration Parameters</title>
<p>The Rumen anonymizer can be configured using the following
configuration parameters:
</p>
<table>
<tr>
<th>Parameter</th>
<th>Description</th>
</tr>
<tr>
<td>
<code>rumen.data-types.classname.preserve</code>
</td>
<td>A comma separated list of prefixes that the <em>Anonymizer</em>
will not anonymize while processing classnames. If
<code>rumen.data-types.classname.preserve</code> is set to
<code>'org.apache,com.hadoop.'</code> then
classnames starting with <code>'org.apache'</code> or
<code>'com.hadoop.'</code> will not be anonymized.
</td>
</tr>
<tr>
<td>
<code>rumen.datatypes.jobproperties.parsers</code>
</td>
<td>A comma separated list of job properties parsers. These parsers
decide how the job configuration parameters
(i.e &lt;key,value&gt; pairs) should be processed. Default is
<code>MapReduceJobPropertiesParser</code>. The default parser will
only parse framework-level MapReduce specific job configuration
properties. Users can add custom parsers by implementing the
<code>JobPropertiesParser</code> interface. Rumen also provides an
all-pass (i.e no filter) parser called
<code>DefaultJobPropertiesParser</code>.
</td>
</tr>
<tr>
<td>
<code>rumen.anonymization.states.dir</code>
</td>
<td>Set this to a location (on LocalFileSystem or HDFS) for enabling
state persistence and/or reload. This parameter is not set by
default. Reloading and persistence of states depend on the state
directory. Note that the state directory will contain the latest
as well as previous states.
</td>
</tr>
<tr>
<td>
<code>rumen.anonymization.states.persist</code>
</td>
<td>Set this to <code>'true'</code> to persist the current state.
Default value is <code>'false'</code>. Note that the states will
be persisted to the state manager's state directory
specified using the <code>rumen.anonymization.states.dir</code>
parameter.
</td>
</tr>
<tr>
<td>
<code>rumen.anonymization.states.reload</code>
</td>
<td>Set this to <code>'true'</code> to enable reuse of previously
persisted state. The default value is <code>'false'</code>. The
previously persisted state will be reloaded from the state
manager's state directory specified using the
<code>rumen.anonymization.states.dir</code> parameter. Note that
the <em>Anonymizer</em> will bail out if it fails to find any
previously persisted state in the state directory or if the state
directory is not set. If the user wishes to retain/reuse the
states across multiple invocations of the <em>Anonymizer</em>,
then the very first invocation of the <em>Anonymizer</em> should
have <code>rumen.anonymization.states.reload</code> set to
<code>'false'</code> and
<code>rumen.anonymization.states.persist</code> set to
<code>'true'</code>. Subsequent invocations of the
<em>Anonymizer</em> can then have
<code>rumen.anonymization.states.reload</code> set to
<code>'true'</code>.

<p></p>
<p>This will anonymize the job details from
<code>file:///home/user/job-trace.json</code> and output it to
<code>file:///home/user/job-trace-anonymized.json</code>.
It will also anonymize the cluster topology layout from
<code>file:///home/user/cluster-topology.json</code> and output it to
<code>file:///home/user/cluster-topology-anonymized.json</code>.
Note that the <code>Anonymizer</code> also supports input and output
files on HDFS.

/**
* A default parser for MapReduce job configuration properties.
* MapReduce job configuration properties are represented as key-value pairs.
* Each key represents a configuration knob which controls or affects the
* behavior of a MapReduce job or a job's task. The value associated with the
* configuration key represents its value. Some of the keys are deprecated. As a
* result of deprecation some keys change or are preferred over other keys,
* across versions. {@link MapReduceJobPropertiesParser} is a utility class that
* parses MapReduce job configuration properties and converts the value into a
* well defined {@link DataType}. Users can use the
* {@link MapReduceJobPropertiesParser#parseJobProperty()} API to process job
* configuration parameters. This API will parse a job property represented as a
* key-value pair and return the value wrapped inside a {@link DataType}.
* Callers can then use the returned {@link DataType} for further processing.
*
* {@link MapReduceJobPropertiesParser} thrives on the key name to decide which
* {@link DataType} to wrap the value with. Values for keys representing
* job-name, queue-name, user-name etc are wrapped inside {@link JobName},
* {@link QueueName}, {@link UserName} etc respectively. Keys ending with *dir*
* are considered as a directory and hence gets be wrapped inside
* {@link FileName}. Similarly key ending with *codec*, *log*, *class* etc are
* also handled accordingly. Values representing basic java data-types like
* integer, float, double, boolean etc are wrapped inside
* {@link DefaultDataType}. If the key represents some jvm-level settings then
* only standard settings are extracted and gets wrapped inside
* {@link DefaultDataType}. Currently only '-Xmx' and '-Xms' settings are
* considered while the rest are ignored.
*
* Note that the {@link MapReduceJobPropertiesParser#parseJobProperty()} API
* maps the keys to a configuration parameter listed in
* {@link MRJobConfig}. This not only filters non-framework specific keys thus
* ignoring user-specific and hard-to-parse keys but also provides a consistent
* view for all possible inputs. So if users invoke the
* {@link MapReduceJobPropertiesParser#parseJobProperty()} API with either
* <"mapreduce.job.user.name", "bob"> or <"user.name", "bob">, then the result
* would be a {@link UserName} {@link DataType} wrapping the user-name "bob".
