Edward Capriolo commented on HIVE-1096: --------------------------------------- I am having trouble uploading with the update diff function of the review board. As I mentioned several times, I really had one simple requirement {noformat} hive -hiveconf DAY=5 -e "LOAD DATA INFILE '/tmp/${DAY}' into logs partition=${DAY}" {noformat} I am all for doing things 100% correct, but this is such a simple thing I am really getting worn out by the endless revisions and doing lots of fancy things just because someone might want to do ${x${y}bla}. Really, I would like to make this ticket go +1, and get on with something more interesting. > Hive Variables > -------------- > > Key: HIVE-1096 > URL: https://issues.apache.org/jira/browse/HIVE-1096 > Project: Hadoop Hive > Issue Type: New Feature > Components: Query Processor > Reporter: Edward Capriolo > Assignee: Edward Capriolo > Fix For: 0.6.0, 0.7.0 > > Attachments: 1096-9.diff, hive-1096-10-patch.txt, > hive-1096-11-patch.txt, hive-1096-12.patch.txt, hive-1096-2.diff, > hive-1096-7.diff, hive-1096-8.diff, hive-1096.diff > > > From mailing list: > --Amazon Elastic MapReduce version of Hive seems to have a nice feature > called "Variables." Basically you can define a variable via command-line > while invoking hive with -d DT=2009-12-09 and then refer to the variable via > ${DT} within the hive queries. This could be extremely useful.
