Denys Kuzmenko commented on HIVE-21397:
---------------------------------------
Hi [~gopalv]. This patch was not intended for Hive, it's ORC related (see
https://issues.apache.org/jira/browse/ORC-477).
https://github.com/apache/orc/pull/373 (branch-1.5)
https://github.com/apache/orc/pull/374 (master)
On Hive side we would need to update orc-core version to 1.5.5, once it's
released.
> BloomFilter for hive Managed [ACID] table does not work as expected

> Key: HIVE-21397

> Steps to Reproduce this issue :
> -----------------------------------------
> 1. Create a HIveManaged table as below :
> -----------------------------------------
> {code:java}
> CREATE TABLE `bloomTest`(
> `msisdn` string,
> `imsi` varchar(20),
> `imei` bigint,
> `cell_id` bigint)
> ROW FORMAT SERDE
> 'org.apache.hadoop.hive.ql.io.orc.OrcSerde'
> STORED AS INPUTFORMAT
> 'org.apache.hadoop.hive.ql.io.orc.OrcInputFormat'
> OUTPUTFORMAT
> 'org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat'
> LOCATION
>
> 'hdfs://c1162-node2.squadron-labs.com:8020/warehouse/tablespace/managed/hive/bloomTest;
>
> TBLPROPERTIES (
> 'bucketing_version'='2',
> 'orc.bloom.filter.columns'='msisdn,cell_id,imsi',
> 'orc.bloom.filter.fpp'='0.02',
> 'transactional'='true',
> 'transactional_properties'='default',
> 'transient_lastDdlTime'='1551206683') {code}
> -----------------------------------------
> 2. Insert a few rows.
> -----------------------------------------
> -----------------------------------------
> 3. Check if bloom filter or active : [ It does not show bloom filters for
> hive managed tables ]
> -----------------------------------------
> {code:java}
> [hive@c1162-node2 root]$ hive --orcfiledump
> hdfs://c1162-node2.squadron-labs.com:8020/warehouse/tablespace/managed/hive/bloomTest/delta_0000001_0000001_0000

> -----------------------------------------
> On Another hand: For hive External tables it works :
> -----------------------------------------
> {code:java}
> CREATE external TABLE `ext_bloomTest`(
> `msisdn` string,
> `imsi` varchar(20),
> `imei` bigint,
> `cell_id` bigint)
> ROW FORMAT SERDE
