Problem Note 59563: Repeated access of a Hadoop table increases the CPU time and the elapsed time
 |  |  |  |  |
When a Hadoop table is accessed repeatedly with SAS/ACCESS® Interface to Hadoop, you might notice increasing real times and CPU times. For example, when you run consecutive CONTENTS procedures or DATA steps, each step is progressively slower.
A workaround is to run each step or procedure as its own job instead of having them be consecutive steps in a single job.
