Subject [jira] [Updated] (MAPREDUCE-2500) MR 279: PB factories are not thread safe
Date Mon, 16 May 2011 23:50:47 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2500?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Siddharth Seth updated MAPREDUCE-2500:
--------------------------------------

    Attachment: MR2500.patch

Factories changed to use a ConcurrentMap - doesn't really matter if two parallel calls end
up creating their own instances (instead of using a cached copy).

Changed FactoryProvider to use a static configuration object if none is provided (instead
of creating a configuration each time)

Changed TypeConverter to use a static RecordFactory. (To be changed later to use a provided
recordFactory)
