Summary: Improve TestFileTruncate#setup by deleting the snapshots
Key: HDFS-8642
URL: https://issues.apache.org/jira/browse/HDFS-8642
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Rakesh R
Assignee: Rakesh R
Priority: Minor

failures will affect all the subsequent unit test cases. One such error has
been observed in the
