Hi,
Like Hive, Is there any split function available to split the string with
special character?
Thanks,

Hi,
How to use null values in list??
Even I changed `store.json.all_text_mode` = true also it is shouting same error.
Query:
select convert_from('{abc:[1,2],bvc:[3,4,null,3]}','json') from tab;
Error: UNSUPPORTED_OPERATION ERROR: Null values are not supported in lists by
default. Please set
Hello,
I do not think this function exist today in Drill. (
https://drill.apache.org/docs/string-manipulation/ )
Maybe you ca create your own Function to achieve this:

Hi Andries, thanks for your support
Bumping the heap or disabling hash_join alone does not cause the query to
completed Drill embedded for Windows behave in a strange way (at least on my
machine):
- When I run Drill alone the query falls OOM, with more than 5GB free memory on
the task
After reading about Parquet Partition Pruning in Drill 1.1, I was wondering
if there is still partitioning based on hive like partitions. I.e. I have
a process that is making a hive table with Parquet files. It's using
Partitions (Directories). Do I need Drill to read that data using the Hive

Both would work i.e query partitioned directories directly using file
system storage plug in or via Hive table.

Would Drill know to partition prune based on directories if it didn't have
the hive metastore to define the partitions at the directory level?

Yes. You can use the dfs plugin in this case.

So , what I am getting at is say a table was created in Hive with PArquet
files
CREATE table hive_parq(field1 STRING, field2 STRING) Partitioned by part1
STRING, part2 STRING STORED as Parquet.
That creates a directory named hive_part, then there will be directories in
under that part1=val1,
John,
Drill has no idea about the names of your partitions since that information
is part of the hive metastore. You can get partition pruning if you modify
your query like below
select * from dfs.hive_parq where dir0=val1; (dir0 is equivalent to part1,
and dir1 would be equivalent to part2)

Hi Parkavi,
This might be a bug in the convert_from function (please log a bug). Try
writing the same json to a file and it should work with all_text_mode set
to true.
