Hi Bhavesh,
I am no expert in this matter but typical Hive use cases don't involve updates.
If your workflow, relies considerably on updating existing data in Hive (i.e.
in HDFS), you might need to re-think your design or the tools you use.

Subject: How to do updation in Hive?
Hello all,
I want to update a columns every time. I have table consists of 50 columns. I
am applying such condition so that every time I need to update a column.
I know that Hive doesn't support UPDATE and If I think about using PARTITION
COLUMN so how can I maintain these columns? Is there any way in Hive which
helps me to update in Hive? or Is there any patch file which helps me to do
this? (But I don't know to how apply Patch files in Linux as I am new to it?)
Please suggest me some solution. I got stuck here and I am not getting what to
do. (I am using hive-0.7.1)
