--------------------------------
Summary: Reduce unnecessary byte-to-string transform operation in
INodesInPath#toString
Key: HDFS-13598
URL: https://issues.apache.org/jira/browse/HDFS-13598
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 3.1.0
Reporter: Yiqun Lin
Every time we invoke {{INodesInPath#toString()}}, we will trigger one time
byte-to-string transform operation.
{code:java}
private String toString(boolean vaildateObject) {
if (vaildateObject) {
validate();
}
final StringBuilder b = new StringBuilder(getClass().getSimpleName())
.append(": path = ").append(DFSUtil.byteArray2PathString(path))
.append("\n inodes = ");
...
}
{code}
But actually we only need to do at most one time. In {{INodesInPath}}, it has
defined one String type variable named {{pathname}} for storing the path string
value. Here we can use {{getPath()}} to to replace
{{DFSUtil.byteArray2PathString(path)}}.
