Ted Yu resolved HBASE-5498.
---------------------------
Resolution: Fixed
Release Note:
This feature adds a new optional configuration parameter:
hbase.bulkload.staging.dir
This defines the path on DFS that HBase will use to create random/secret
directories under.
The default location is /tmp/hbase-staging

> 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.
