Francis Liu updated HBASE-5498: ------------------------------- Attachment: HBASE-5498_trunk_2.patch Updated trunk patches incorporating review comments. Except for the following: -added coprocessor hooks for the new SecureBulkLoadCoprocessors (I'd like to address this as part of the coprocessor refactor for 0.96) -SecureTestUtil continues to load SecureBulkLoad by default, this is better for consistency and overall testing -Support for federation > Secure Bulk Load > ---------------- > > Key: HBASE-5498 > URL: https://issues.apache.org/jira/browse/HBASE-5498 > Project: HBase > Issue Type: Improvement > Components: security > Reporter: Francis Liu > Assignee: Francis Liu > Fix For: 0.94.3, 0.96.0 > > Attachments: HBASE-5498_94.patch, HBASE-5498_94.patch, > HBASE-5498_draft_94.patch, HBASE-5498_draft.patch, HBASE-5498_trunk_2.patch, > HBASE-5498_trunk.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.
