-----------------------------------
Summary: Output streams closed with IOUtils suppressing write
errors
Key: HADOOP-15085
URL: https://issues.apache.org/jira/browse/HADOOP-15085
Project: Hadoop Common
Issue Type: Bug
Reporter: Jason Lowe
There are a few places in hadoop-common that are closing an output stream with
IOUtils.cleanupWithLogger like this:
{code}
try {
...write to outStream...
} finally {
IOUtils.cleanupWithLogger(LOG, outStream);
}
{code}
This suppresses any IOException that occurs during the close() method which
could lead to partial/corrupted output without throwing a corresponding
exception. The code should either use try-with-resources or explicitly close
the stream within the try block so the exception thrown during close() is
properly propagated as exceptions during write operations are.
