Issue Type: Bug
Components: Functions - Drill
Affects Versions: 1.13.0
Environment: My POC info:
* 2 EC2 "r4.xlarge" with 30G of memory
* both are running zookeeper for load distribution
* both are running drillbits.
* Storage
** S3, dfs
* Connection drivers: JDBC
* File Types/info: Json, max size between: 7MB - 75MB, and around 2200
different filles
Reporter: Melvin Ramos
hello
We are evaluating apache drill 1.13.0 to be used on our data lake initiative.
Problem:
I was able to select data when I ran small (around 3-50 files) query data which
is fine, but when I collapse all on month (2200 different json files) I get
into problems.
on initial run it looks like its doing its work, but after executing the actual
work, both drillbits seems to wait on each other and see when they are done,
and nothing returns on my SQL analyzer query (Dbeaver)
Here are last few lines after the run.
