Subject [jira] [Commented] (HBASE-4552) multi-CF bulk load is not atomic across column families
Date Tue, 11 Oct 2011 03:38:30 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4552?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13124660#comment-13124660
] 

Ted Yu commented on HBASE-4552:
-------------------------------

Toward the end of LoadIncrementalHFiles.tryLoad() we can utilize startEndKeys of the underlying
table to group (possibly split) HFiles by their first row keys.
Then the new bulkLoadHFile() method would be called by doBulkLoad().

> Currently the bulk load API simply imports one HFile at a time. With multi-column-family
support, this is inappropriate, since different CFs show up separately. Instead, the IPC endpoint
should take a of CF -> HFiles, so we can online them all under a single region-wide lock.
