hadoop – Hive UDF protocols not available

I am trying to transfer my Hive UDF logs either to the console or to a file. However, it doesn't seem to work. My Hive UDF uses log4j with console appenders.

I tried to make them available log4j.properties File while connecting to beeline. But even then I don't see any logs on the console.

 !connect jdbc:hive2://abc.com:8449/;ssl=true;transportMode=http;httpPath=gateway/emr-cluster-top/hive;sslTrustStore=/etc/pki/ca-trust/extracted/java/cacerts;trustStorePassword=changeit;hive.log4j.file=/home/gshah03/log4j.properties

After that, however, when I tried to check that hive.log4j.file it complains that it is not set.

d> set hive.log4j.file;
|              set              |
| hive.log4j.file is undefined  |

I cannot set this property at runtime.

HIVE SQL IF ELSE statement, then create different tables

Here is the logic I want:

if hour(CURRENT_TIMESTAMP) % 2 = 0
    THEN create table table_1 AS
    **same select statement**

else if hour(CURRENT_TIMESTAMP) % 2 = 1
    THEN create table table_2 AS
    **same select statement**

If the hour is an odd / even number, the name of the build table differs. The select statement is exactly the same.

How do you do that?

hive – SQL filter only if each unique value contains more than N records

Here is my sample SQL statement:

FROM my_table
WHERE DAY = '${date}'

For example 3 unique names in the "Name" column: Alice, Bob, Clark.

Alice has 5 rows, Bob has 9 rows, Clark has 12 rows.

I want to add a filter if rows with the same value are> 10 rows. & # 39; Clark & ​​# 39; fulfilled in this case.

How do I add that? under WHERE?

Attempt to restart an Ambari-managed cluster and receive errors related to the launch of the Timeline Service V2.0 Reader service:

I did not change any configuration or install anything new between the reboot. Just stop cluster services and try to restart them. Not sure what this error message means. Tips or bug fixes for debugging?
