Vivek Ratan commented on HADOOP-1993:
-------------------------------------
very simple fix. org.apache.hadoop.record.compiler.JVector.genCompareTo() needs
to increment its level (call incrLevel()) at the beginning and decrement it at
end. This lets it generate unique variable names.
This fix is part of the patch submitted for HADOOP-1883.
> Incorrect code in Java stubs created by Record I/O compiler for
> vector<vector> type

> Key: HADOOP-1993
> URL: https://issues.apache.org/jira/browse/HADOOP-1993
> Project: Hadoop
> Issue Type: Bug
> Reporter: Vivek Ratan
> Assignee: Vivek Ratan
> Priority: Minor
>
> If a 'vector of vectors' field is present in a DDL, the Java code generated
> by Record I/O contains errors in the _compareTo()_ method. For example, if
> the DDL is
> {code}
> class s1 {
> vector<vector<int>> slkl;
> }
> {code}
> then s1.compareTo() contains code that cannot be compiled (duplicate local
> variables).
