I always meant for these more complicated layouts to work - now I know they do > check/fix conversion of unbucketed non-acid to acid > --------------------------------------------------- > > Key: HIVE-17214 > URL: https://issues.apache.org/jira/browse/HIVE-17214 > Project: Hive > Issue Type: Sub-task > Components: Transactions > Reporter: Eugene Koifman > Assignee: Eugene Koifman > Priority: Minor > Attachments: HIVE-17214.01.patch > > > bucketed tables have stricter rules for file layout on disk - bucket files are direct children of a partition directory. > for un-bucketed tables I'm not sure there are any rules > for example, CTAS with Tez + Union operator creates 1 directory for each leg of the union > Supposedly Hive can read table by picking all files recursively. > Can it also write (other than CTAS example above) arbitrarily? > Does it mean Acid write can also write anywhere? > Figure out what can be supported and how can existing layout can be checked? Examining a full "ls -l -R" for a large table could be expensive. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
