NoClassDefFoundError when creating a custom hive UDF

Hi, I have created a custom Hive UDF that has external JAR dependencies. I have added those jars to the Hive session using 'add jar' but when I try to create my function, I get a NoClassDefFoundError on the dependency class. I am on Hive 0.81 running in Amazon EMR. This is what happens when I t

Yes, a little bit. IMHO, these flags could be assigned only for aliases with condition on 'on' clause. Then, I think, even a byte (8 flags) could be enough in most cases. I'll do that if time permits. 2013/7/1 wzc1989 : > hi navis: > look at the patches in (HIVE-3411, HIVE-4206, HIVE-4212, HIVE-

Re: Hive Table to CSV file

you gotta admit that's kinda funny. Your stderr output shows not only once but three times where it put the output and in fact how many rows it put there. and to top it off it reported 'SUCCESS'. but you're saying there's nothing there? now. call me crazy but i would tend to believe hive over y

Hello there, Thanks a lot for the response. Do you mean creating an external table?I have also tried deleting "ouputregex", but same result. And the jar is also added. Warm Regards, Tariq cloudfront.blogspot.com On Mon, Jul 1, 2013 at 1:39 PM, Matouk IFTISSEN wrote: > Hello, > try to

sorry for the spam. but one correction. json_pp appears to be part of the perl core so if you have a modern perl you may already have it installed. On Mon, Jul 1, 2013 at 1:31 PM, Stephen Sprague wrote: > ok. so i just learned of a perl script called "json_pp" (for json > pretty_prrint) that

Re: unable to partition the table

ok. so i just learned of a perl script called "json_pp" (for json pretty_prrint) that is a binary included in the distro for the perl JSON module. You gotta figure there are analogous tools in other languages as well but given this is a binary it doesn't matter much what language its written in -

Re: Correct way of using regexserde

Hello, try to delete "output.regex" = "%1$s" and store your data in file then pricise where the file is located STORED AS TEXTFILE LOCATION '/..'; and assure that you add the jar "hive-contrib-0.10.0.jar" in the session or you have it in all Hadoop tasktrackers like this: add jar path_where_i

Experience of Hive local mode execution style

Hi all, Would anybody have any comments or feedback about the hive local mode execution? It is advertised as providing a boost to performance for small data sets. It seem to fit nicely when running unit/integration tests on single node or virtual machine. My exact questions are the following :

FW: Continuing/FAILED/ATTEMPT error with udf

Hi all, I ran into errors that I cannot explain when using a java User Defined Function: - The UDF runs fine on smallquery, I am therefore confident on my ADD JAR/CREATE TEMPORARY code; - The error is only raised on complex queries/ high volume data sets; - The jobs complain first about a "java.

回复： different outer join plan between hive 0.9 and hive 0.10

hi navis: look at the patches in (HIVE-3411, HIVE-4206, HIVE-4212, HIVE-3464), I understand what you mean by "hive tags rows a filter mask as a short for outer join, which can contain 16 flags. " . I wonder why not choose Long or int which can contain 64/32 tags. Does adding one Long/int in eve
