You have defined a parquet only table. It interprets your CSV file as parquet.
You can for instance define 2 tables:
* one external for the CSV file
* one table for the parquet file
Afterwards you select from the first table and insert in the second table.

Dear all,
I have developed several custom input formats (e.g. for the Bitcoin
blockchain) including a HiveSerde, which are open source.
I plan to develop for my HadoopOffice inputformat also a HiveSerde, but I
wonder if I should continue to use mapred.* apis or if i should use
mapreduce.*
My inpu

You have to write a custom hiveserde format to pass tblproperties as
inputformat properties, but check the source code of the serde you used.

What is the create table statement? Do you parse the tblproperties in the
HiveSerde? Do you have exceptions in the log?

What is your hardware setup?
Are the bloom filters necessary on all columns? Usually they make only sense
for non-numeric columns. Updating bloom filters take time and should be avoided
where they do not make sense.
Can you provide an example of the data and the select queries that you execute

Dear all,
I prepared a small Serde to analyze Bitcoin blockchain data with Hive:

There are some example queries, but I will add some in the future.
Additionally, more unit tests will be added.

Hi Lars,
I think this is a valid concern and your proposal sounds good to me.

There must be some log4j configuration file in the hive configuration
folder where you can do this.

Additionally, although it is a PoC you should have a realistic data model.
Furthermore, following good data modeling practices should be taken into
account. Joining on a double is not one of them. It should be int.
Furthermore, double is a type that is in most scenarios rarely used. In the
business
Is this also for varchar ?

Hi 韦,
You must be a little bit more precise. What is the error message? What is
your setup (OS, JDK version..) ?
Thank you.
Best regards
