Impala Does Not Store Or Interpret Timestamps Using The Local Timezone

http://www.cloudera.com/documentation/archive/impala/2-x/2-1-x/topics/impala_langref_unsupported.html?scroll=langref_hiveql_delta
   - *Impala does not store or interpret timestamps using the local 
   timezone*, to avoid undesired results from unexpected time zone issues. 
   Timestamps are stored and interpreted relative to UTC. This difference can 
   produce different results for some calls to similarly named date/time 
   functions between Impala and Hive. See Impala Date and Time Functions 
    for details about the Impala functions."
Any plans to fix this?
We currently load all data using Hive and Spark and query from Impala. This 
Impala's inconsistency with what Spark and Hive does gives a lot of 
problems that we don't know how to fix..
It would be great to at least have a session- or server-level setting to 
control this Impala's timestamp problem.
Is there any JIRA for this to fix or implement or workaround?
Thanks,
Ruslan

It seems this one - https://issues.cloudera.org/browse/IMPALA-1773
This incompatibility bug makes timestamp datatype useless in Impala.
We have time in Impala jumping +7/8 hours (Mountain time), even though
original time
was always 00:00:00. We use Hive/Spark when load data to Hadoop, and
tried to use "UTC" or "America/Denver" during loads, but can't make time on
Impala
side to be consistent / fixed to 00:00:00 as in source systems.

Hi Ruslan,
I think you want to use the startup flag -convert_legacy_hive_parquet_utc_timestamps=true. More information can be found at http://www.cloudera.com/documentation/enterprise/latest/topics/impala_timestamp.html . Let me know if you have questions.

of server? Hi, can anyone explain mysql 5.0.54 handling of replication between two servers with inconstant /etc/localtime (but the same real clock time for UTC) the same time. Server localtime is GMT+1, created col is a date, updated_at col is a timestamp When this replicated to the other server which had localtime set to GMT, and then after it replicated I changed localtime to

[email protected], [email protected] Hello, We are running MySQL server Ver 3.23.8 on a Linux system. We have a table that contains a field whose type is MODIFIED | timestamp(14) We would like to find out if there an easy way in MySQL to convert the date that is on the MODIFIED field (timestamp) to GMT time without an external program.

Hi,   The system timezone on our datanodes is UTC.  I d like the date and time functions on impala to use the local timezone ie 'America/Los_Angeles'. I added export TZ='America/Los_Angeles'  to the impala init scripts and restarted the statestore and impala-server services.  However, when I run a query like  select from_unixtime(1379540985) from dual; Query: select from_unixtime(1379540985
Hi all! I always have the problem to convert the "last update" times on PEARWeb to my local timezone... What would you think about switching to UTC?

All, I will be recording timezone information based on user input using the time zone names from mysql.time_zone_name - names like 'America/Los_Angeles'. When recording this information, do I store the full name or just the 'time_zone_id' which is present in mysql.time_zone_name ? thanks Per Jessen, Zürich
Hi. I am trying to change the timezone for MySQL (version 3.23.56) but it does not seem to work. Currently the timezone is set to "MDT" (I think its the default for MySQL). I added the following line to /etc/my.cnf at the [mysqld] section: set-variable = timezone=CST But when I try to stop and start the daemon, it does not want to start: Starting mysqld daemon with databases from
Hi everyone, since I'm using the shared hosting, I can't change the default timezone for MySql. Question is: is there any query that I could launch in my connect.php before other queries to make my timezone change? For instance, I make a mysql_query("SET CHARACTER_SET_DATABASE='utf8'") or die ("Unable to change database charset: ".mysql_error()); and a mysql_query("SET NAMES 'utf8
This is probably a familiar error for anyone using PHP: I know *what* this error means, I don't quite understand why PHP considers the system's timezone unreliable? All other programming languages I've used just use the systems timezone without problems, and most applications (servers applications, desktop apps) just use the system setting. For example, in C: #include #include int
Hi! Is it possible to use timezones in server side javascript? I'd like to use a grouping function to group by timestamps of type Date() trucated to the date portion. The following grouping functions will work as long as the timestamps are stored in localtime: -------------------- 8< -------------------- function(d) {   return {     'date': new Date(       d.uploadDate.getFullYear
Hi I'm importing database records into SOLR using the DIH. My dates are not getting imported correctly and they're getting a timezone offset added to them (+4 hours). I know SOLR tends to be timezone agnostic from the documentation I've read so far, but what could this be? Any tips on where to look would be greatly appreciated. I'm using the trunk version of SOLR built on 11/1. Mike
