[jira] [Created] (PIG-3181) MultiStorage -
java.lang.OutOfMemoryError: Java heap space
Fabian Alenius created PIG-3181:
-----------------------------------
Summary: MultiStorage - java.lang.OutOfMemoryError: Java heap space
Key: PIG-3181
URL: https://issues.apache.org/jira/browse/PIG-3181
Project: Pig
Issue Type: Bug
Components: piggybank
Affects Versions: 0.10.0
Reporter: Fabian Alenius
Hi, I have a script that looks like this:
a = load '/input' as (f1, f2);
a = group a by f1;
a = foreach logs {
generate group, a.f2;
}
store logs into '/output/' using org.apache.pig.piggybank.storage.MultiStorage('/output/', '0');
But for some reason it fails with:
