Francis Liu commented on HBASE-5498: ------------------------------------ Laxman, what are version are you running it on? I deployed the patch on 0.94 and didn't hit that problem (wasn't sure if trunk was deployable). I hit other problems tho, give me a day or two to iron things out and I'll post a patch. > 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.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.
