Re: LOAD multiple files with glob

Sat, 24 Nov 2012 05:15:43 -0800 

Hello,

Thanks for your suggestion!
I switch my avro variable to avro = load '$INPUT' USING AvroStorage();

However I get the same results this way:

$ pig -p INPUT=/data/2012/trace_ejb3/2012-01-02.avro avro-test.pig
which: no hbase in (:/usr/lib64/qt-3.3/bin:/usr/java/jdk1.6.0_33/bin/:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin)

Hi,
I dont have a system to test it right now, but I have been passing it using 
under parameter -p and it works.
change line to accept parameters like avro = load '$INPUT' USING 
AvroStorage();
bin/pig -p INPUT="/data/2012/trace_ejb3/2012-**01-0[12].avro" <scriptName>
I think if you dont give double quotes then the expansion is done by OS. 

Please let us know if it doesnt work...

Using Pig 0.10.0-cdh4.1.2, i try to load those files, and describe them. 

REGISTER 'hdfs:///lib/avro-1.7.2.jar';
REGISTER 'hdfs:///lib/json-simple-1.1.**1.jar';
REGISTER 'hdfs:///lib/piggybank.jar';
DEFINE AvroStorage org.apache.pig.piggybank.**storage.avro.AvroStorage();
avro = load '/data/2012/trace_ejb3/2012-**01-01.avro' USING AvroStorage(); 

describe avro;


This works, same with 2012-01-02.avro.

However, as soon as i want to include multiple files, no dice.

avro = load '/data/2012/trace_ejb3/2012-**01-{01,02}.avro' USING
AvroStorage();
gives me:
2012-11-23 21:41:07,475 [main] ERROR org.apache.pig.tools.grunt.**Grunt - 
ERROR 2999: Unexpected internal error. null
Caused by: java.net.URISyntaxException: Illegal character in path at index 
30: /data/2012/trace_ejb3/2012-01-**{01,02}.avro
avro = load '/data/2012/trace_ejb3/2012-**01-*.avro' USING AvroStorage(); 
gives me:
Schema for avro unknown.

avro = load '/data/2012/trace_ejb3/2012-**01-0[12].avro' USING
AvroStorage();
also gives me:
Caused by: java.net.URISyntaxException: Illegal character in path at index 
31: /data/2012/trace_ejb3/2012-01-**0[12].avro
What am i doing wrong here? According to http://hadoop.apache.org/docs/** 
r0.21.0/api/org/apache/hadoop/**fs/FileSystem.html#globStatus%**
28org.apache.hadoop.fs.Path%29<http://hadoop.apache.org/docs/r0.21.0/api/org/apache/hadoop/fs/FileSystem.html#globStatus%28org.apache.hadoop.fs.Path%29>, this should all be acceptable input? 

Thanks in advance!

Kind regards,

Bart
