> When running below command to load data into bucketed tables it is not
> loading into specified partition instead loaded into default partition.
> LOAD DATA INPATH '/tmp/files/000000_0' OVERWRITE INTO TABLE call
> PARTITION(year_partition=2012, month=12);
> SELECT * FROM call WHERE year_partition=2012 AND month=12; --> returns 0 rows.
> {code}
> CREATE TABLE call(
> date_time_date date,
> ssn string,
> name string,
> location string)
> PARTITIONED BY (
> year_partition int,
> month int)
> CLUSTERED BY (
> date_time_date)
> SORTED BY (
> date_time_date ASC)
> INTO 1 BUCKETS
> STORED AS ORC;
> {code}
> If set hive.exec.dynamic.partition to false, it fails with below error.
> {code}
> Error: Error while compiling statement: FAILED: SemanticException 1:18
> Dynamic partition is disabled. Either enable it by setting
> hive.exec.dynamic.partition=true or specify partition column values. Error
> encountered near token 'month' (state=42000,code=40000)
> {code}
> When we "set hive.strict.checks.bucketing=false;", the load works fine.
> This is a behaviour imposed by HIVE-15148 to avoid incorrectly named data
> files being loaded to the bucketed tables. In customer use case, if the files
> are named properly with bucket_id (00000_0, 00000_1 etc), then it is safe to
> set this flag to false.
> However, current behaviour of loading into default partitions when
> hive.strict.checks.bucketing=true and partitions specified, was a bug
> injected by HIVE-19311 where the given query is re-written into a insert
> query (to handle incorrect file names and Orc versions) but missed to
> incorporate the partitions specs to it.
