Xiao Chen updated HADOOP-14524:
-------------------------------
Description:
See HADOOP-14523 for motivation. Credit to [[email protected]] for reporting
initially there.
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.
