Subject [jira] Commented: (HADOOP-4501) [Hive] CLI not supporting multiline queries from an input file
Date Mon, 03 Nov 2008 21:50:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12644818#action_12644818

---------------------------------------

Hi Jeremy,

Couple of issues
1) Should line 166 be in inside the if (m.matches()) condition?
2) line 185: i think if loop gets executed even if the last line doesn't end with a ';'
3) I think processLine should be used instead of processCmd. Otherwise the code can't handle
cmds like 'select a.* from tabA a; select \nb.* from tabB b'
4) also, could you update the patch with new code available for 0.17. There have been some
changes that make the commands case insensitive.

It will be good if you can make similar changes to code that handles interactive commands
(in main()). If not we can do that in a separate JIRA as well.

> calling "hive -f filename" allows to pass HQL queries from a file.
> but the queries can't be on multiple lines as we would expect by reading Hive documentation.
> a proposed fix is to modify CliDriver.processReader.
