Hi, after switching to Hive 4.0 and Tez on yarn I've noticed that simple
fetch queries run much longer. I have following configuration:
hive.fetch.task.conversion=more
hive.fetch.task.conversion.threshold=1073741824
hive.limit.optimize.enable=true hive.limit.optimize.fetch.max=50000
hive.limit.optimize.limit.file=10 hive.limit.pushdown.memory.usage=0.1
hive.limit.row.max.size=100000 and query select * from tbl limit 100
runs on Tez containers instead of being run internaly inside hiveserver2. How
to configure fetch task conversion properly as even clicking on Hue has bad
experience with data previews run on Tez on yarn... Regards, Wojtek
