Andrew Purtell commented on HBASE-5498: --------------------------------------- @Ram Unless we have a scanner type interface for validating bulk loaded files, we can't exclude KVs on a qualifier basis. See above comment on that. Francis' patch is providing the first facility, a decision point for moving files in place. Since it operates on HFiles, the best we can do as you note is check for table and column family permissions. We should document this clearly. IMHO, later we can add (if necessary) a scanner like interface for filtering by security policy the HFiles after they have been moved in place. > Secure Bulk Load > ---------------- > > Key: HBASE-5498 > URL: https://issues.apache.org/jira/browse/HBASE-5498 > Project: HBase > Issue Type: Improvement > Components: mapred, security > Reporter: Francis Liu > Assignee: Francis Liu > Fix For: 0.96.0 > > Attachments: HBASE-5498_draft_94.patch, HBASE-5498_draft.patch > > > Design doc: > https://cwiki.apache.org/confluence/display/HCATALOG/HBase+Secure+Bulk+Load > 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. -- This message is automatically generated by JIRA.
