@rbanerjee, to answer your question, yes, temporary tables are independent and isolated between sessions for the same user. Here, https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-TemporaryTables, it says "A table that has been created as a temporary table will only be visible to the current session"   I have verified that. As the same user I created a temporary table of the same name in two concurrent Beeline sessions. They are independent, as confirmed by INSERT/SELECT statements and conclusively by their locations in HDFS:   Session 1: SHOW CREATE TABLE... LOCATION ... /tmp/hive/hive/4d4e879d-5806-425e-9051-d764b117c71d/_tmp_space.db/d3b5f635-1251-4cda-be59-79555c8643fd   Session 2: SHOW CREATE TABLE... LOCATION  .. /tmp/hive/hive/15049889-fc99-4890-b3eb-0a5d22c73083/_tmp_space.db/ac5a2d3c-a61f-4797-afa4-c88940a10147   ... View more
