Pierre Lacave created HADOOP-14346:
--------------------------------------
Summary: CryptoOutputStream throws IOException if stream is closed
which is not the standard OutputStream behaviour
Key: HADOOP-14346
URL: https://issues.apache.org/jira/browse/HADOOP-14346
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 2.7.3
Reporter: Pierre Lacave
With Druid and Hadoop 2.7.3 I see that calls to flush() on a closed
CryptoOutputStream throws IOException.
Although flushing closed stream is dodgy, the culprit is actually
CryptoOutputStream, according to the java documentation it look actually
authorised.
The OutputStream java doc
(http://docs.oracle.com/javase/8/docs/api/java/io/OutputStream.html#flush())
shows that flush should behave like close(), which allows being called on a
closed stream without exception (as opposed to write() and others which clearly
says should throw an exception)
