> When PTF is used over a large partitions result could be corrupted

> Key: HIVE-11583
> URL: https://issues.apache.org/jira/browse/HIVE-11583
> Project: Hive
> Issue Type: Bug
> Components: PTF-Windowing
> Affects Versions: 0.14.0, 0.13.1, 0.14.1, 1.0.0, 1.2.0, 1.2.1
> Environment: Hadoop 2.6 + Apache hive built from trunk
> Reporter: Illya Yalovyy
> Assignee: Illya Yalovyy
> Priority: Critical
> Attachments: HIVE-11583.patch
>
>
> Dataset:
> Window has 50001 record (2 blocks on disk and 1 block in memory)
> Size of the second block is >32Mb (2 splits)
> Result:
> When the last block is read from the disk only first split is actually
> loaded. The second split gets missed. The total count of the result dataset
> is correct, but some records are missing and another are duplicated.
> Example:
> {code:sql}
> CREATE TABLE ptf_big_src (
> id INT,
> key STRING,
> grp STRING,
> value STRING
> ) ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t';
> LOAD DATA LOCAL INPATH '../../data/files/ptf_3blocks.txt.gz' OVERWRITE INTO
> TABLE ptf_big_src;
> SELECT grp, COUNT(1) cnt FROM ptf_big_trg GROUP BY grp ORDER BY cnt desc;
> ---
> -- A 25000
> -- B 20000
> -- C 5001
> ---
> CREATE TABLE ptf_big_trg AS SELECT *, row_number() OVER (PARTITION BY key
> ORDER BY grp) grp_num FROM ptf_big_src;
> SELECT grp, COUNT(1) cnt FROM ptf_big_trg GROUP BY grp ORDER BY cnt desc;
> --
> -- A 34296
> -- B 15704
> -- C 1
> ---
> {code}
> Counts by 'grp' are incorrect!
