[jira] Created: (MAPREDUCE-2317) HadoopArchives throwing
NullPointerException while creating hadoop archives (.har files)
HadoopArchives throwing NullPointerException while creating hadoop archives (.har files)
----------------------------------------------------------------------------------------
Key: MAPREDUCE-2317
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2317
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: harchive
Affects Versions: 0.20.1, 0.23.0
Environment: windows
Reporter: Devaraj K
Priority: Minor
While we are trying to run hadoop archive tool in widows using this way, it is giving the below exception.
java org.apache.hadoop.tools.HadoopArchives -archiveName temp.har D:/test/in E:/temp
{code:xml}
java.lang.NullPointerException
at org.apache.hadoop.tools.HadoopArchives.writeTopLevelDirs(HadoopArchives.java:320)
at org.apache.hadoop.tools.HadoopArchives.archive(HadoopArchives.java:386)
at org.apache.hadoop.tools.HadoopArchives.run(HadoopArchives.java:725)
at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65)
at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:79)
at org.apache.hadoop.tools.HadoopArchives.main(HadoopArchives.java:739)
{code}
I see the code flow to handle this feature in windows also,
{code:title=Path.java|borderStyle=solid}
/** Returns the parent of a path or null if at root. */
public Path getParent() {
String path = uri.getPath();
int lastSlash = path.lastIndexOf('/');
int start = hasWindowsDrive(path, true) ? 3 : 0;
if ((path.length() == start) || // empty path
(lastSlash == start && path.length() == start+1)) { // at root
return null;
}
String parent;
if (lastSlash==-1) {
parent = CUR_DIR;
} else {
int end = hasWindowsDrive(path, true) ? 3 : 0;
parent = path.substring(0, lastSlash==end?end+1:lastSlash);
}
return new Path(uri.getScheme(), uri.getAuthority(), parent);
}
{code}
