Troubleshooting
Problem
Although the NameNode service may become busy due to several activities, certain Trash configurations can result in a huge volume of deleted files being "expunged" at a single point in time.
Symptom
During normal operation using IBM BigInsights, the Hadoop NameNode service may become unresponsive preventing job execution; in a High Availability environment using Zookeeper, this may result in Zookeeper considering the NameNode service is unavailable and instigate failover, which may be repeated several times.
