Re: Need Help on Eclipse + JDK to load hive project !!
I use Eclipse 3.4.0 (3.4.1 also works) with Java 6. Try the instruction from here http://wiki.apache.org/hadoop/Hive/GettingStarted/EclipseSetup I use hadoop-0.17.2.1 version instead of hadoop-0.19 since the former works well with running unit tests.

Hi, I have a linux box running Red Hat Linux 4. I tried with many eclipse and jdk versions but finally eclipse 3.2.1 worked with jdk1.5 java run time. I could not load source files from hive into a project. COULD SOMEONE PLEASE TELL ME THE FOLLOWING :: (1) Is the version for eclipse + jdk fine for hive development ? (2) How to load the whole hive project onto eclipse ? Regards, shyam_sar...@yahoo.com

Would I lose any recent features if I do not use hadoop-0.19.0 version ? --- On Sat, 1/31/09, Prasad Chakka pra...@facebook.com wrote: From: Prasad Chakka pra...@facebook.com Subject: Re: Need Help on Eclipse + JDK to load hive project !!

[jira] Commented: (HIVE-262) outer join gets some duplicate rows in some scenarios
[ https://issues.apache.org/jira/browse/HIVE-262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=12669286#action_12669286 ] Namit Jain commented on HIVE-262: - Ashish suggested the following approach: Based on join conditions, create a set of all tables being joined (no outer join), and if one of them is null for a given value, all of them become null. For example, A join B on A.c1=B.c1 join C on A.c1=C.c1 right outer join D on A.c1=D.c1 A,B,C belong to the same group (since A joins with B and A joins with C). So, for a given key (c1), if there is no row corresponding to either of A, B, or C - assume that there is no row for all of them for that key. That works for the example above, and the approach is different from the patch outer join gets some duplicate rows in some scenarios - Key: HIVE-262 URL: https://issues.apache.org/jira/browse/HIVE-262 Project: Hadoop Hive Issue Type: Bug Components: Query Processor Affects Versions: 0.2.0 Reporter: Namit Jain Assignee: Namit Jain Priority: Blocker Fix For: 0.2.0 Attachments: patch.262.1.txt, patch262.2.txt SELECT * FROM src src1 JOIN src src2 ON (src1.key = src2.key AND src1.key 10) RIGHT OUTER JOIN src src3 ON (src1.key = src3.key AND src3.key 20); returns duplicate rows for outer join -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
