[jira] [Updated] (SPARK-10484) [Spark SQL] Come across lost
task(timeout) or GC OOM error when cross join happen
[ https://issues.apache.org/jira/browse/SPARK-10484?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yi Zhou updated SPARK-10484:
----------------------------
Description:
Found that it lost task or GC OOM when below cross join happen. The left big table is ~1.2G in size and the right small table is ~2.2K.
Key SQL
{code:sql}
SELECT
CONCAT(s_store_sk,"_", s_store_name ) AS store_ID,
pr_review_date,
pr_review_content
FROM product_reviews pr, temp_stores_with_regression stores_with_regression
WHERE locate(lower(stores_with_regression.s_store_name), lower(pr.pr_review_content), 1) >= 1 ;
{code}
Physical Plan
{code:sql}
TungstenProject [concat(cast(s_store_sk#456L as string),_,s_store_name#457) AS store_ID#446,pr_review_date#449,pr_review_content#455]
Filter (locate(lower(s_store_name#457),lower(pr_review_content#455),1) >= 1)
CartesianProduct
HiveTableScan [pr_review_date#449,pr_review_content#455], (MetastoreRelation bigbench, product_reviews, Some(pr))
HiveTableScan [s_store_sk#456L,s_store_name#457], (MetastoreRelation bigbench, temp_stores_with_regression, Some(stores_with_regression))
