Suresh Srinivas created HDFS-4676:
-------------------------------------
Summary: TestHDFSFileSystemContract should set MiniDFSCluster
variable to null to free up memory
Key: HDFS-4676
URL: https://issues.apache.org/jira/browse/HDFS-4676
Project: Hadoop HDFS
Issue Type: Bug
Components: test
Reporter: Suresh Srinivas
Assignee: Suresh Srinivas
Priority: Minor
TestHDFSFileSystemContract should reset the cluster member to null in order to
make garbage collection quickly collect large chunk of memory associated with
MiniDFSCluster. This avoids OutOfMemory errors.
