Teddy Choi created HIVE-20827: --------------------------------- Summary: Inconsistent results for empty arrays Key: HIVE-20827 URL: https://issues.apache.org/jira/browse/HIVE-20827 Project: Hive Issue Type: Bug Reporter: Teddy Choi Assignee: Teddy Choi
LazySimpleDeserializeRead parses an empty array wrong. For example, a line ',' in a text file table with a delimiter ',' and schema 'array<int>, array<array<string>>' shows \[null\], \[\[""\]\], instead of \[\], \[\] with MapReduce engine and vectorized execution enabled. LazySimpleDeserializeRead has following code; {code:java} switch (complexField.complexCategory) { case LIST: { // Allow for empty string, etc. final boolean isNext = (fieldPosition <= complexFieldEnd); {code} Empty string value read should be only applied to string families, not to other data types. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
