ASF GitHub Bot updated HDFS-11115:
----------------------------------
Labels: pull-request-available (was: )
> Remove bytes2Array and string2Bytes
> -----------------------------------
>
> Key: HDFS-11115
> URL: https://issues.apache.org/jira/browse/HDFS-11115
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs, hdfs-client
> Reporter: Sahil Kang
> Priority: Minor
> Labels: pull-request-available
>
> In DFSUtilClient.java we have something like:
> {code: language=java}
> public static byte[] string2Bytes(String str) {
> try {
> return str.getBytes("UTF-8");
> } catch (UnsupportedEncodingException e) {
> throw new IllegalArgumentException("UTF8 decoding is not supported", e);
> }
> }
> static String bytes2String(byte[] bytes, int offset, int length) {
> try {
> return new String(bytes, offset, length, "UTF-8");
> } catch (UnsupportedEncodingException e) {
> throw new IllegalArgumentException("UTF8 encoding is not supported", e);
> }
> }
> {code}
> Using StandardCharsets, these methods become trivial:
> {code: language=java}
> public static byte[] string2Bytes(String str) {
> return str.getBytes(StandardCharsets.UTF_8);
> }
> static String bytes2String(byte[] bytes, int offset, int length) {
> return new String(bytes, offset, length, StandardCharsets.UTF_8);
> }
> {code}
> I think we should remove these methods and use StandardCharsets whenever we
> need to convert between bytes and strings.
