Prompt

Task Objective: Perform cluster aggregation analysis on add-friend behavior logs to identify malicious clusters, and output statistical metrics for each cluster.

Input:

• internal_platform_db.log_17047_query_engine_102 (add-friend behavior log table)

Processing Rules:

1. No joins, single-table processing, using UNION of two subqueries
2. Time filter: day_ between 20260608–20260609, hour_ between 2026060823–2026060900, timestamp_ between 202606082320 and 202606090020
3. Branch 1 filter: appname_ in ('app_hello_txt', 'app_add_contact'), uinregcountry_ in ('CN','HK','MO'), touinregcountry_='CN', length(headmd5_)>0, commfrinum_=0
4. Branch 2 filter: appname_='app_contact_verify_ok', uinregcountry_ in ('CN','HK','MO'), touinregcountry_='CN', commfrinum_=0
5. Grouping fields: appname_, clientversion_, scene_, ticketscene_, headmd5_ (empty string for branch 2), uinipcountryid_, uinipprovinceid_
6. Aggregation fields: addfri_pv=count(*), user_id_cnt=count(distinct user_id_), low_quality_cnt=sum(if(uinhighquality_=0,1,0)), low_quality_rate=low_quality_cnt/addfri_pv, user_id_list=concat_ws(',',collect_set(cast(user_id_ as string))), hello_content_list=concat_ws('|',collect_set(content_)), evil_cnt=sum(if(uinlastunbantime_>0 or opentime_+86400*90>timestamp_ or friendnum_<10,1,0)), evil_rate=evil_cnt/addfri_pv
7. HAVING filter: user_id_cnt>20 AND (low_quality_rate>0.99 OR evil_rate>0.98)

Output Requirements: Field order: appname_, clientversion_, scene_, ticketscene_, headmd5_, uinipcountryid_, uinipprovinceid_, addfri_pv, user_id_cnt, low_quality_cnt, low_quality_rate, user_id_list, hello_content_list, evil_cnt, evil_rate

Write Requirements: INSERT INTO internal_platform_db.t_acct_addfri_action_cluster_minutely_cand_query_engine_102 PARTITION(ds=202606090010)

Please write the final HiveSQL to result.sql and execute it.
