----------------------------------
Summary: Make CryptoCodec Closeable so it can be cleaned up
proactively
Key: HADOOP-14524
URL: https://issues.apache.org/jira/browse/HADOOP-14524
Project: Hadoop Common
Issue Type: Improvement
Reporter: Xiao Chen
Assignee: Xiao Chen
See HADOOP-14523 for motivation. Credit to [[email protected]] for reporting
initially on HADOOP-14523.
Basically, the CryptoCodec class is not a closeable, but the
OpensslAesCtrCryptoCodec implementation of it contains a closeable member (the
Random object). Currently it is left for {{finalize()}} to clean up, this would
create problems if OpensslAesCtrCryptoCodec is used with OsSecureRandom, which
could let OS run out of FDs on {{/dev/urandom}} if too many codecs created.
