It seems that column `link_crtd_date` is of type `timestamp` and you therefore
partition by date including time, which produces a huge amount of directories.
I assume your intent is to partition by date (partition_date=yyyy-MM-dd or
year=yyyy/month=MM/day=dd) so you need to format/split your timestamp
accordingly, for example:
-- partitioned by 'yyyy-MM-dd'
INSERT OVERWRITE TABLE bsl12.email_edge_lyh_partitioned2
PARTITION (partition_date)
SELECT
date_format(link_crtd_date, 'yyyy-MM-dd') as partition_date,
*
FROM bsl12.email_edge_lyh_mth1;
-- partitioned by year/month/day
INSERT OVERWRITE TABLE bsl12.email_edge_lyh_partitioned2
PARTITION (year, month, day)
SELECT
year(link_crtd_date, 'yyyy-MM-dd') as year,
month(link_crtd_date, 'yyyy-MM-dd') as month,
day(link_crtd_date, 'yyyy-MM-dd') as day,
*
FROM bsl12.email_edge_lyh_mth1;
