huianyi edited a comment on issue #238: [LIVY-689] Deliver stage process message to the end user using thriftserver URL: https://github.com/apache/incubator-livy/pull/238#issuecomment-560985424 @mgaido91 The previous link you pointed actually is another feature we can implement(process bar), you can check it here, [HiveStatement.java#L381](https://github.com/apache/hive/blob/209096a71b25a3d75dca1930f825c8c10b99d2b9/jdbc/src/java/org/apache/hive/jdbc/HiveStatement.java#L381) , [BeelineInPlaceUpdateStream.java#L39](https://github.com/apache/hive/blob/209096a71b25a3d75dca1930f825c8c10b99d2b9/beeline/src/java/org/apache/hive/beeline/logs/BeelineInPlaceUpdateStream.java#L39) Like I previous said, I can support this in a new PR. > > > Beeline from Hive 2.2 has in-place progress bar hive.server2.in.place.progress > > > https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.server2.in.place.progress > > > (I think it works only with tez - would be nice if this would work with Livy too ) > > > > > > Would be better to support this if it is not a big effort. > > After reading hive related code, this needs write some new classes to implement this feature, which might cause this PR large, if you don not mind, I'd love to open a new PR to support this. ProcessBar is great in real-time interaction environment, but it can not work well if we do scheduling jobs, which we need print the job's status in seperate lines. > In this way, we need to store nothing on Livy server memory. By default setting, we can keep each session keep not more than 100 rows, actually under normal circumstances, client will get these message immediately, this might not put much memory pressure on Livy server side.
