Subject [jira] [Commented] (HBASE-17123) Add postBulkLoadHFile variant that notifies the final paths for the hfiles
Date Tue, 05 Dec 2017 04:45:00 GMT

Anoop Sam John commented on HBASE-17123:
----------------------------------------

CPs backward compat we can break IMO. We broke it left and right already.  I believe even
the pre hook had some return. We changed that to void. Post hook also better we change to
void return IMO.  Ya in some other issue we can fix.

> Currently the postBulkLoadHFile() hook passes the same familyPaths parameter which it
receives as method parameter.
> See code in SecureBulkLoadManager :
> {code}
>        loaded = region.getCoprocessorHost().postBulkLoadHFile(familyPaths, loaded);
> {code}
> Meaning, the paths are not final, moved paths of the loaded hfiles.
> This issue is to add a variant which notifies the final paths of the loaded hfiles.
