> Key: HDFS-12559
> URL: https://issues.apache.org/jira/browse/HDFS-12559
> Project: Hadoop HDFS
> Issue Type: Sub-task

> Priority: Major

> This test creates 1000 containers and reads them back 5 containers at a time and verifies that we did get back all containers. On my laptop, it takes 11s to finish but on some slow Jenkins machine this could take longer time.
> Current the whole test suite {{TestContainerPersistence}} has a timeout rule of 5 min. Need to understand why RocksDB open is taking such a long time as shown in the stack below.
> {code}
> java.lang.Exception: test timed out after 300000 milliseconds
