[jira] [Updated] (SPARK-27266) Support ANALYZE TABLE to collect
tables stats for cached catalog views
[ https://issues.apache.org/jira/browse/SPARK-27266?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Takeshi Yamamuro updated SPARK-27266:
-------------------------------------
Description:
The master doesn't support ANALYZE TABLE to collect tables stats for catalog views even if they are cached;
{code:java}
scala> sql(s"CREATE VIEW v AS SELECT 1 c")
scala> sql(s"CACHE LAZY TABLE v")
scala> sql(s"ANALYZE TABLE v COMPUTE STATISTICS")
org.apache.spark.sql.AnalysisException: ANALYZE TABLE is not supported on views.;
at org.apache.spark.sql.execution.command.AnalyzeTableCommand.run(AnalyzeTableCommand.scala:38)
at org.apache.spark.sql.execution.command.ExecutedCommandExec.sideEffectResult$lzycompute(commands.scala:70)
at org.apache.spark.sql.execution.command.ExecutedCommandExec.sideEffectResult(commands.scala:68)
at org.apache.spark.sql.execution.command.ExecutedCommandExec.executeCollect(commands.scala:79){code}
Since SPARK-25196 has supported an ANALYZE command to collect column statistics for cached catalog view, we could support table stats, too.
