Hi again,
Are incrimental timestamp values (long) being encoded in Parquet as
incremental values?
(This option in parquet to refrain from storing complete numbers and store
only the delta between numbers to save space)

Hi Andries, hi all,
great stuff,
drillbit=localhost instead of
zk=local
did the trick.
Could you elaborate a little more, on what the difference is or where to
retrieve additional information / documentation?
Thx

Hi,
On the Drill GUI Query page, there is radio button named "Query Type" with
3 options SQL | PHYSICAL | LOGICAL
Any idea what PHYSICAL | LOGICAL mean here?
Regards
SQL one means the SQL language. Usually, we use this one.
Logical, physical plans are plans (think of it as scripts) for drill engine to
run. They are usually generated by machine, so they are used mainly for
development/experiment purpose.

Drill can run in 2 modes - Embedded and Distributed.
In Distributed Mode it uses ZK for keeping track of all the Drillbits in a
Drill cluster. When connecting to a a distributed cluster you can either
connect direct to a single drill or use ZK to get a list if all drillbits and
then get connect

What are the thoughts for combining all the data in the individual
directories? Is there an option to replace like in Hive?

I am doing some "active" loading of data into json files on MapRFS.
Basically I have feeds pulling from a message queue and outputting the
JSON messages.
I have a query that is doing aggregations on all the data that seem to work
90% of the time.
The other 10%, I get this error:
Error: DATA_REA
Hi.
I read your dilemma. Would a trap in program to handle this ERROR or Exception
work for you in this case and address it by skip around the trouble? My guess
is you have a timing condition gone astray somewhere and you need to assure all
states are timed correctly.
But what do I know. Good lu
See DRILL-2424 and DRILL-1131
Incomplete records/files can cause issues, in Drill 1.2 hey have added the
ability to ignore data files with a .prefix.
Perhaps copy files in over NFS using a . prefix and then rename once copied on
the DFS.
I had the same issue with Flume data streaming in and inc
Well I have one program writing data via Python to MapRFS in a directory
that Drill is reading, so yes, I have two different programs reading and
writing data. What I am looking for here is knowing I may have this
scenario where a read may occur before a write is complete, can I just
have Drill ig
Great feature and this fixes my problem. All I do is in my python script
when I open a file, it opens with the .prefix. When I "close" it I rename
it without the . prefix. Easy fix. Thanks for the pointer Andries!

I have some JSON that includes a field that is a array type, and some of
those fields are json nulls.
As seen in my other recent post about views and the "Please set
`store.json.all_text_mode` I am getting this error here.
Like I put in my other post, I don't want to set this at a system level,
