HI, all :
i am newbie at hive, i got this error when i was creating a table using "select from " syntax,
my input is as following:
`hive>create table longyuan_web.tmp_recent_week_data_cookies as
select u from longyuan_web.ods_mbw_user_pv where dt>='2018-07-19'
and dt<='2018-07-25'and platform='31'
and u is not null and length(u)>=32
and os='ios' group by u`
i get this error:FAILED: SemanticException 0:0 Error creating temporary folder on: hdfs://hadoop-bd-ns01/hive/warehouse/longyuan_web.db. Error encountered near token 'TOK_TMP_FILE'
i am pretty sure i am on the right cluster and the original table is also on this cluster
what this 'TOK_TMP_FILE'?
thank you so much!!

Mostly the issue is user doesn't have access to write to longyuan_web database.
Please check that you have correct permissions and then try to execute then execute CTAS again.
Jira ticket addressing same exact issue is here

That's right.
(I assume Your select query runs good as stand-alone)
You have read access in longyuan_web db. But not write access.
Work around is... Try to create the table in some other db where you have write access, like....
`hive>create table **xxx_web**.tmp_recent_week_data_cookies as select u from longyuan_web.ods_mbw_user_pv where dt>='2018-07-19' and dt<='2018-07-25'and platform='31' and u is not null and length(u)>=32 and os='ios' group by u` as select u from longyuan_web.ods_mbw_user_pv where dt>='2018-07-19' and dt<='2018-07-25'and platform='31' and u is not null and length(u)>=32 and os='ios' group by u`
Where xxx_web is the Db where you have write access.
