Li Jin commented on ARROW-1431: ------------------------------- This issue is fixed by https://github.com/apache/arrow/pull/1290 > [Java] JsonFileReader doesn't intialize some vectors approperately > ------------------------------------------------------------------- > > Key: ARROW-1431 > URL: https://issues.apache.org/jira/browse/ARROW-1431 > Project: Apache Arrow > Issue Type: Bug > Components: Java > Reporter: Li Jin > Priority: Major > > One example is for ListVector, the JsonFileReader sets the validity, offset > and data, but doesn't set `lastSet` variable in the ListVector instance. > ArrowFileReader works correct before it invokes `loadFieldBuffers` and > intialize `lastSet` correctly: > https://github.com/apache/arrow/blob/master/java/vector/src/main/java/org/apache/arrow/vector/complex/ListVector.java#L120 > This doesn't break integration tests but can cause weird bugs when people > call methods on the vector read from json. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
