--------------------------------------

             Summary: Bug in ValidWriteIdList comparison in AcidUtils
                 Key: IMPALA-10637
                 URL: https://issues.apache.org/jira/browse/IMPALA-10637
             Project: IMPALA
          Issue Type: Bug
          Components: Catalog
            Reporter: Sourabh Goyal


There is a bug in [this|https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/util/AcidUtils.java#L752] line of code in AcidUtils.java. 


Example scenario: 

For validWriteIdLists: 

ValidWriteIdList a = new ValidReaderWriteIdList("default.test:1:1:1:");
ValidWriteIdList b = new ValidReaderWriteIdList("default.test:1:9223372036854775807::");

AcidUtils.compare(a, b) currently returns 1 whereas the expected answer is -1.
