Class Anonymizer

    java.lang.Object
      org.apache.hadoop.contrib.failmon.Anonymizer

    public class Anonymizer

extends Object

This class provides anonymization to SerializedRecord objects. It anonymizes all hostnames, ip addresses and file names/paths that appear in EventRecords gathered from the logs and other system utilities. Such values are hashed using a cryptographically safe one-way-hash algorithm (MD5).

Constructor Summary
`Anonymizer()`

Method Summary
`static SerializedRecord` | `anonymize(EventRecord er)` Anonymize hostnames, ip addresses and file names/paths that appear in fields of an EventRecord, after it gets serialized into a SerializedRecord.
`static SerializedRecord` | `anonymize(SerializedRecord sr)` Anonymize hostnames, ip addresses and file names/paths that appear in fields of a SerializedRecord.
`static String` | `getMD5Hash(String text)` Create the MD5 digest of an input text.
