--------------------------------------
Summary: OOM because of too many DFSClient instances in
TokenCache.obtainTokensForFileSystems
Key: TEZ-3566
URL: https://issues.apache.org/jira/browse/TEZ-3566
Project: Apache Tez
Issue Type: Bug
Reporter: Harish Jaiprakash

When FileSystem cache is disabled, invoking
TokenCache.obtainTokensForFileSystems creates lot of FileSystem objects which
are unique and stored in a hash set. This takes up lot of memory and causes OOM.
