> Short summary:
> Security as it stands does not cover the bulkLoadHFiles() feature. Users 
> calling this method will bypass ACLs. Also loading is made more cumbersome in 
> a secure setting because of hdfs privileges. bulkLoadHFiles() moves the data 
> from user's directory to the hbase directory, which would require certain 
> write access privileges set.
> Our solution is to create a coprocessor which makes use of AuthManager to 
> verify if a user has write access to the table. If so, launches a MR job as 
> the hbase user to do the importing (ie rewrite from text to hfiles). One 
> tricky part this job will have to do is impersonate the calling user when 
> reading the input files. We can do this by expecting the user to pass an hdfs 
> delegation token as part of the secureBulkLoad() coprocessor call and extend 
> an inputformat to make use of that token. The output is written to a 
> temporary directory accessible only by hbase and then bulkloadHFiles() is 
> called.
