> Implement a variant of ElasticByteBufferPool which uses weak references for
> garbage collection.
> -----------------------------------------------------------------------------------------------
>
> Key: HADOOP-18105
> URL: https://issues.apache.org/jira/browse/HADOOP-18105
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: common, fs
> Reporter: Mukund Thakur
> Assignee: Mukund Thakur
> Priority: Major
> Labels: pull-request-available
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Currently in hadoop codebase, we have two classes which implements byte
> buffers pooling.
> One is ElasticByteBufferPool which doesn't use weak references and thus could
> cause memory leaks in production environment.
> Other is DirectBufferPool which uses weak references but doesn't support
> caller's preference for either on-heap or off-heap buffers.
>
> The idea is to create an improved version of ElasticByteBufferPool by
> subclassing it ( as it is marked as public and stable and used widely in hdfs
> ) with essential functionalities required for effective buffer pooling. This
> is important for the parent Vectored IO work.
