Impala Administration
As an administrator, you monitor Impala's use of resources and take action when necessary to keep Impala running smoothly and avoid conflicts with other Hadoop components running on the same cluster. When you detect that an issue has happened or could happen in the future, you reconfigure Impala or other components such as HDFS or even the hardware of the cluster itself to resolve or avoid problems.
