--------------------------------------------
Summary: TestJsonLoaderStorage fails with IBM JDK 6/7
Key: PIG-3309
URL: https://issues.apache.org/jira/browse/PIG-3309
Project: Pig
Issue Type: Improvement
Components: build
Affects Versions: 0.11.1
Environment: IBM J9 VM 1.6.0 SR13 FP1; IBM J9 VM 1.7.0 SR4 FP1
Reporter: Leonardo Rangel Augusto
Priority: Minor
Fix For: 0.11.2
TestJsonStorageLoader fails due to small differences in the way HashMaps are
printed out. The HashMap specification
(http://docs.oracle.com/javase/1.5.0/docs/api/java/util/HashMap.html) mentions
that "This class makes no guarantees as to the order of the map; in particular,
it does not guarantee that the order will remain constant over time.", so PIG
testcases should not rely on the order in which the HashMap items are printed
out.
testJsonLoaderStorage1 explicitly does this comparison:
Testcase: testJsonLoaderStorage1 took 2.25 sec
