BELUGA BEHR created HIVE-20158:
----------------------------------
Summary: Do Not Print StackTraces to STDERR in
Base64TextOutputFormat
Key: HIVE-20158
URL: https://issues.apache.org/jira/browse/HIVE-20158
Project: Hive
Issue Type: Improvement
Components: Contrib
Affects Versions: 3.0.0, 4.0.0
Reporter: BELUGA BEHR
https://github.com/apache/hive/blob/6d890faf22fd1ede3658a5eed097476eab3c67e9/contrib/src/java/org/apache/hadoop/hive/contrib/fileformat/base64/Base64TextOutputFormat.java
{code}
try {
String signatureString = job.get("base64.text.output.format.signature");
if (signatureString != null) {
signature = signatureString.getBytes("UTF-8");
} else {
signature = new byte[0];
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
{code}
The {{UnsupportedEncodingException}} is coming from the {{getBytes}} method
call. Instead, use the {{CharSet}} version of the method and it doesn't throw
this explicit exception so the 'try' block can simply be removed. Every JVM
will support UTF-8.
