OUtils#copyBytes methods should not close streams that are passed in as
parameters
----------------------------------------------------------------------------------
Key: HADOOP-5943
URL: https://issues.apache.org/jira/browse/HADOOP-5943
Project: Hadoop Core
Issue Type: Bug
Components: io
Reporter: Hairong Kuang
Fix For: 0.21.0
The following methods in IOUtils close the streams that are passed in as
parameters. Calling these methods can easily trigger findbug OBL: Method may
fail to clean up stream or resource (OBL_UNSATISFIED_OBLIGATION). A good
practice should be to close a stream in the same method where the stream is
opened.
public static void copyBytes(InputStream in, OutputStream out, int buffSize,
boolean close)
public static void copyBytes(InputStream in, OutputStream out, Configuration
conf, boolean close)
These methods should be deprecated.
