casey c56ba5149c Infra scripts: Only attempt to kill processes owned by the current user
This is for compatibility with docker containers. Before this patch,
when the scripts were run on the docker host, the scripts  would try
to kill the mini-cluster in the docker containers and fail because they
didn't have permissions (the user is different). Now the scripts will
only try to kill mini-cluster processes that were started by the current
user.

Also some psutil availability checks were removed because psutil is now
provided by the python virtualenv.

Welcome to Impala

Lightning-fast, distributed SQL queries for petabytes of data stored in Apache Hadoop clusters.

Impala is a modern, massively-distributed, massively-parallel, C++ query engine that lets you analyze, transform and combine data from a variety of data sources:

  • Best of breed performance and scalability.
  • Support for data stored in HDFS, Apache HBase and Amazon S3.
  • Wide analytic SQL support, including window functions and subqueries.
  • On-the-fly code generation using LLVM to generate CPU-efficient code tailored specifically to each individual query.
  • Support for the most commonly-used Hadoop file formats, including the Apache Parquet (incubating) project.
  • Apache-licensed, 100% open source.
