--------------------------------
Summary: Fix byte to string encoding issues in hadoop-hdfs
Key: HDFS-7512
URL: https://issues.apache.org/jira/browse/HDFS-7512
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Xiaoyu Yao
In hadoop-hdfs, there are some bytes to string conversion using default
charsets, which is flagged by findbugs 3.0 because the behavior of conversion
depends on the platform settings of encoding. This jira proposes to fix the
findbugs warnings below:
