Igor Kabiljo updated HIVE-2939: ------------------------------- Priority: Minor (was: Major) > LazyArray.getList changes array it previously returned > ------------------------------------------------------- > > Key: HIVE-2939 > URL: https://issues.apache.org/jira/browse/HIVE-2939 > Project: Hive > Issue Type: Bug > Components: UDF > Affects Versions: 0.8.1 > Reporter: Igor Kabiljo > Priority: Minor > > Simple query like: > SELECT a, e > FROM ikabiljo_test_string_array > LATERAL VIEW EXPLODE(a) x1 AS e > (table contains one column - ARRAY<STRING> - and has one row - [b,c,a] ) > fails with ConcurrentModificationException, since LazyArray.getList changes > the cached array it returns. > LazyArray.getList can easily: > - return cached array if present, without clearing and refiling. Hive is > already not going to work properly if you change input parameters in an UDF. > If that doesn't sound good - it can return Collections.unmodifiableList > - or just not cache anything > Same is true for LazyMap.getMap -- This message is automatically generated by JIRA.
