Karthik Kambatla updated HADOOP-10591: -------------------------------------- Target Version/s: 2.6.0 (was: 2.5.0) > Compression codecs must used pooled direct buffers or deallocate direct > buffers when stream is closed > ----------------------------------------------------------------------------------------------------- > > Key: HADOOP-10591 > URL: https://issues.apache.org/jira/browse/HADOOP-10591 > Project: Hadoop Common > Issue Type: Bug > Affects Versions: 2.2.0 > Reporter: Hari Shreedharan > Assignee: Colin Patrick McCabe > Attachments: HADOOP-10591.001.patch > > > Currently direct buffers allocated by compression codecs like Gzip (which > allocates 2 direct buffers per instance) are not deallocated when the stream > is closed. Eventually for long running processes which create a huge number > of files, these direct buffers are left hanging till a full gc, which may or > may not happen in a reasonable amount of time - especially if the process > does not use a whole lot of heap. > Either these buffers should be pooled or they should be deallocated when the > stream is closed. -- This message was sent by Atlassian JIRA (v6.2#6252)
