Hari Shreedharan created HADOOP-10591: -----------------------------------------
Summary: 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 Reporter: Hari Shreedharan 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)
