@milind pandit You can get access time using FileStatus#getAccessTime() as follows: public class HdfsAtime {
private static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");
public static void main(String[] args) throws IOException {
FileSystem fs = FileSystem.get(new Configuration());
printFileStatus(fs, new Path(args[0]));
fs.close();
}
private static void printFileStatus(FileSystem fs, Path root) throws IOException {
FileStatus[] fss = fs.listStatus(root);
for (FileStatus status : fss) {
if (status.isDirectory()) {
printFileStatus(fs, status.getPath());
} else {
System.out.println(
sdf.format(new Date(status.getAccessTime())) + " "
+ sdf.format(new Date(status.getModificationTime())) + " "
+ Path.getPathWithoutSchemeAndAuthority(status.getPath()));
}
}
}
}
And, in order to enable access time, you may need to set dfs.namenode.accesstime.precision an appropriate value (set 0 by HDP default). <property>
<name>dfs.namenode.accesstime.precision</name>
<value>3600000</value>
</property>
