Date Tue, 15 Jun 2010 16:13:23 GMT
TestAlgebraicEvalLocal failures due to OOM
------------------------------------------

                 Key: PIG-1450
                 URL: https://issues.apache.org/jira/browse/PIG-1450
             Project: Pig
          Issue Type: Test
    Affects Versions: 0.7.0, 0.8.0
            Reporter: Eli Collins
             Fix For: 0.8.0


6 test cases in TestAlgebraicEvalLocal fail on trunk and release 0.7 across a number of different
machines.

Example failure:

Unable to open iterator for alias myid
org.apache.pig.impl.logicalLayer.FrontendException: ERROR 1066: Unable to open iterator for
alias myid
        at org.apache.pig.PigServer.openIterator(PigServer.java:521)
        at org.apache.pig.test.TestAlgebraicEvalLocal.testGroupUniqueColumnCount(TestAlgebraicEvalLocal.java:236)
Caused by: java.io.IOException: Job terminated with anomalous status FAILED
        at org.apache.pig.PigServer.openIterator(PigServer.java:515)

Probably due to OOMs in the log:
