I tried to update my record in hive previous version and also tried out
update in hive 0.14.0. The newer version which support hive.
I created a table with 3 buckets with 180 MB. In my warehouse the data get
stored into 3 different blocks
delta_0000012_0000012
--- Block ID: 1073751752
--- Block ID: 1073751750
--- Block ID: 1073751753
After doing an update
I am getting 2 directories
delta_0000012_0000012
--- Block ID: 1073751752
--- Block ID: 1073751750
--- Block ID: 1073751753
AND
delta_0000014_0000014
---Block ID: 1073752044
Ie the blocks are not reused
Whether my understanding is correct?
Any pointers?
