Halting due to Out Of Memory Error...Exit code 255 - hive - tez - java heap - GC

Hello All,

Can some one please help me fix this OOM error||heap issue , while running query from hive

Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "client DomainSocketWatcher"

-----------

Map1 - stays in initializing state and not moving to running state with OOM error

Hi @manojamr

Step 1: Could you run the following commands to gather column statistics for all the table that is involved in the query.

analyze table <TABLE-NAME> compute statistics;
analyze table <TABLE-NAME> compute statistics for columns;

Reference: https://cwiki.apache.org/confluence/display/Hive/StatsDev

Step 2: set the following property in session level
set hive.tez.container.size=10240 ;
set hive.tez.java.opts=-Xmx8192m;
set tez.runtime.io.sort.mb=4096;
set tez.task.resource.memory.mb=7680;
set tez.am.resource.memory.mb=10240;
set tez.am.launch.cmd-opts=-Xmx8192m;

If Step2 got succes ignore step 3.

Step 3:
Re-run the job at the beeline session-level.

If the job fails again, I would request the below details.

1. Complete query,
2. Beeline console output,
3. QueryId of the job
4. HS2 and HMS logs and
5. Application logs.

@Shifu - Thanks for the inputs

Finally by modifying these parameters job started running
set tez.am.java.opts=-Xmx14745m;
set tez.am.resource.memory.mb=16384;

However this hive-tez job is taking almost 9.5 hours to get the query executed completely .
Total number of records in the table approx (1.2 billion) - 1137722667

Below is the query used . If you have any suggestion which could improve the query execution time

that would be great

-----------------------------------------------------------------

select station_id, parameter_name, unit_name, statistic_name, latitude, longitude, from_unixtime(UNIX_TIMESTAMP(observed_date, "yyyy-MM-dd'T'HH:mm:ss'Z'"),"yyyy-MM-dd") as observed_date, avg(value) as value from today_data.price where parameter_name= 'AIR_TEMPERATURE' and unit_name = 'DEGREES_CELSIUS' and statistic_name='MEAN' and year(from_unixtime(UNIX_TIMESTAMP(observed_date, "yyyy-MM-dd'T'HH:mm:ss'Z'"),"yyyy-MM-dd HH:mm:ss")) = 2021 group by station_id, parameter_name, unit_name, statistic_name, latitude, longitude, from_unixtime(UNIX_TIMESTAMP(observed_date, "yyyy-MM-dd'T'HH:mm:ss'Z'"),"yyyy-MM-dd");

Hi @manojamr

I am glad to know your original issue got resolved.

As per your last comment, your Query took 9.5 hours to get complete.
In this case, we may need to check whether there is a delay or hungriness, or resource crunch or it is normal.

To figure out that we may need beeline console output, QueryId, Application log, all HS2 and HMS logs. It would be great if you create a case with Cloudera so we would be happy to assist you.
