--------------------------------
Summary: DFSOutputStream can silently drop data if DataStreamer
crashes with a non-I/O exception
Key: HDFS-7199
URL: https://issues.apache.org/jira/browse/HDFS-7199
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs-client
Affects Versions: 2.5.0
Reporter: Jason Lowe
Priority: Critical
If the DataStreamer thread encounters a non-I/O exception then it closes the
output stream but does not set lastException. When the client later calls
close on the output stream then it will see the stream is already closed with
lastException == null, mistakently think this is a redundant close call, and
fail to report any error to the client.
