BELUGA BEHR created HIVE-17998:
----------------------------------
Summary: Use FastDateFormat instead of SimpleDateFormat for
TimestampWritable
Key: HIVE-17998
URL: https://issues.apache.org/jira/browse/HIVE-17998
Project: Hive
Issue Type: Improvement
Components: Serializers/Deserializers
Affects Versions: 3.0.0, 2.4.0
Reporter: BELUGA BEHR
Priority: Trivial
Currently Hive is using this ThreadLocal/SimpleDateFormat setup to work around
the thread-safety limitations of SimpleDateFormat.
Let us simply drink the Apache Commons champagne and use thread-safe
{{org.apache.commons.lang.time.FastDateFormat}} instead.
{code:java|title=org.apache.hadoop.hive.serde2.io.TimestampWritable}
private static final ThreadLocal<DateFormat> threadLocalDateFormat =
new ThreadLocal<DateFormat>() {
@Override
protected DateFormat initialValue() {
return new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
}
};
{code}
