ASF GitHub Bot updated HIVE-22224:
----------------------------------
Labels: parquet pull-request-available (was: parquet)
> Support Parquet-Avro Timestamp Type
> -----------------------------------
>
> Key: HIVE-22224
> URL: https://issues.apache.org/jira/browse/HIVE-22224
> Project: Hive
> Issue Type: Bug
> Components: Database/Schema
> Affects Versions: 2.3.5, 2.3.6
> Reporter: cdmikechen
> Assignee: cdmikechen
> Priority: Major
> Labels: parquet, pull-request-available
> Fix For: 2.3.7
>
>
> When user create an external table and import a parquet-avro data with 1.8.2
> version which supported logical_type in Hive2.3 or before version, Hive can
> not read timestamp type column data correctly.
> Hive will read it as LongWritable which it actually stores as
> long(logical_type=timestamp-millis).So we may add some codes in
> org.apache.hadoop.hive.serde2.objectinspector.primitive.WritableTimestampObjectInspector.java
> to let Hive cast long type to timestamp type.
> Some code like below:
>
> public Timestamp getPrimitiveJavaObject(Object o) {
> if (o instanceof LongWritable) {
> return new Timestamp(((LongWritable) o).get());
> }
> return o == null ? null : ((TimestampWritable) o).getTimestamp();
> }
>
