Per https://issues.apache.org/jira/browse/HDFS-245, symbolic link is implemented in hdfs for several years, but cdh5 still not able to recognize "hadoop fs -nl" command.
So is symbolic link feature available in hdfs? If so, how to create one?
We have been hoping for the reintroduction of HDFS symlinks for several years.
Q: Is there any development at all going on related to HDFS symlinks?
From a distance, it seems like this should relatively easy ... all pathname resolution takes place on the namenode.
Q: Does anyone have any simple/brief insight as to why HDFS symlinks might be technically challenging?
I might be missing something here but if symbolic links are not supported in HDFS, what is the significance of the method createSymlink in FileContext class?
