Hi, Symbolic Links are supported in Hadoop 2.0 using FileContext's objects createSymLink()<http://hadoop.apache.org/docs/current/api/org/apache/hadoop/fs/FileContext.html> method.
I am looking at using symlinks heavily in a program that places all files for the previous month in Hadoop Archives (HARs), but I am wondering if using symlinks consume Namenode memory similar to having small files in HDFS which would defeat the purpose of placing these in HARs and bring me roundrobin to the original problem of small files. Also, the reason I want to use symlinks is so that when the files are HAR'ed (and as a consequence moved) I don't have to update HBase (my file metastore) with the new file location. What is the memory footprint of symlinks in a NameNode? -- This email, including any attachments, contains information that is privileged, confidential, and/or otherwise exempt from disclosure under applicable law.
