--------------------------------
Summary: Container launching code suppresses close exceptions
after writes
Key: YARN-7595
URL: https://issues.apache.org/jira/browse/YARN-7595
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Reporter: Jason Lowe
There are a number of places in code related to container launching where the
following pattern is used:
{code}
try {
...write to stream outStream...
} finally {
IOUtils.cleanupWithLogger(LOG, outStream);
}
{code}
Unfortunately this suppresses any IOException that occurs during the close()
method on outStream. If the stream is buffered or could otherwise fail to
finish writing the file when trying to close then this can lead to
partial/corrupted data without throwing an I/O error.
