How to select current date in Hive SQL

Question

How do we get the current system date in Hive? In MySQL we have select now(), can any one please help me to get the query results. I am very new to Hive, is there a proper d

Yes... I am using Hue 3.7.0 - The Hadoop UI and to get current date/time information we can use below commands in Hive:

SELECT from_unixtime(unix_timestamp()); --/Selecting Current Time stamp/

SELECT CURRENT_DATE; --/Selecting Current Date/

SELECT CURRENT_TIMESTAMP; --/Selecting Current Time stamp/

However, in Impala you will find that only below command is working to get date/time details:

SELECT from_unixtime(unix_timestamp()); --/Selecting Current Timestamp /

Hope it resolves your query :)
