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

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.
