java.lang.String cannot be cast to java.lang.Integer
Hi, I got very strange exception. 80693 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1066: Unable to open iterator for alias ordered. Backend error : java.lang.String cannot be cast to java.lang.Integer 14/05/30 11:53:22 ERROR grunt.Grunt: ERROR 1066: Unable to open iterator for alias ordered. Backend error : java.lang.String cannot be cast to java.lang.Integer In my pig script below, z is integer but pig complains as it is String. query = load 'fino32' USING org.apache.hcatalog.pig.HCatLoader() as ( date: chararray, u: float, v: float, t: float, zone: int, z: int); ordered = ORDER query BY z; dump ordered; Any suggestion is appreciated.

Re: java.lang.String cannot be cast to java.lang.Integer
Hi, Handle null values, check if the content of column z is definitely integer values, ensure that no whitecharacters are included (e.g. 11 ). Ultimately, you can read the z column as chararray and process it with udf. This will give you chance to log the faulty record. Tell if any of this removed the problem.

Re: java.lang.String cannot be cast to java.lang.Integer
Hi, column z is integer and not null, so I do not understand why I got cast exception.

Issue when building Pig
Hi all, I am trying to build and install Pig 0.12.1. I downloaded the tar file and unpackaged it. Now I am trying to build Pig so that it can work with the version of Hadoop that I am using - version 2.4.0. In order to do this, I enter the command: ant clean jar-all -Dhadoopversion=23 However, during the build I get an error saying that it can't find the file jetty-6.1.26.zip. Here is some of the stack trace: [cid:image001.png@01CF7C01.5F877C80] It seems like it is trying to download the file from a few sites, but the file can't be found at any of them. Any suggestions or advice would be much appreciated. Thanks, Andrew Botelho Intern EMC Corporation Education Services Email: andrew.bote...@emc.commailto:andrew.bote...@emc.com
Re: Issue when building Pig
I've seen this before, and I believe it's some env issue because I can't reproduce it on my laptop while my colleague can on his laptop. If you look at ivy.xml, ivy shouldn't download jetty-6.1.26.zip at all. I couldn't figure out why this happens in certain environments.

Re:java.lang.String cannot be cast to java.lang.Integer
How about using the explicit cast like ordered = ORDER query BY (int)z; Alcaid -- Original -- From: Patcharee Thongtra;patcharee.thong...@uni.no; Date: Fri, May 30, 2014 06:02 PM To: useruser@pig.apache.org; Subject: java.lang.String cannot be cast to java.lang.Integer Hi, I got very strange exception. 80693 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1066: Unable to open iterator for alias ordered.
