Shixiong Zhu resolved SPARK-29099.
----------------------------------
Resolution: Duplicate
> org.apache.spark.sql.catalyst.catalog.CatalogTable.lastAccessTime is not set
> ----------------------------------------------------------------------------
>
> Key: SPARK-29099
> URL: https://issues.apache.org/jira/browse/SPARK-29099
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.4.4
> Reporter: Shixiong Zhu
> Priority: Major
>
> I noticed that
> "org.apache.spark.sql.catalyst.catalog.CatalogTable.lastAccessTime" is always
> 0 in my environment. Looks like Spark never updates this field in metastore
> when reading a table. This is fine considering the cost to update it when
> reading a table is high.
> However, "Last Access" in "describe extended" always shows "Thu Jan 01
> 00:00:00 UTC 1970" and this is confusing. Can we show something alternative
> to indicate it's not set?
