Xiaoyu Yao commented on HDFS-8597:
----------------------------------
The test takes dfs.datanode.data.dir from "hdfs-default.xml"
{code}
<name>dfs.datanode.data.dir</name>
<value>file://${hadoop.tmp.dir}/dfs/data</value>
{code}
The location ends up as
file://C:\Users\xiaoyu\hadoop\trunk\hadoop\hadoop-hdfs-project\hadoop-hdfs\target/test/dfs/data
before passing to Util.stringAsURI(). However, the Java URI class cannot
handle mix '/' and '\' separator in the path, which causes the exception.
The fix is to use Java Path class to normalize the path separator and then
convert it to URI.
