Chris Nauroth created HADOOP-13726: -------------------------------------- Summary: Enforce that FileSystem initializes only a single instance of the requested FileSystem. Key: HADOOP-13726 URL: https://issues.apache.org/jira/browse/HADOOP-13726 Project: Hadoop Common Issue Type: Improvement Components: fs Reporter: Chris Nauroth
The {{FileSystem}} cache is intended to guarantee reuse of instances by multiple call sites or multiple threads. The current implementation does provide this guarantee, but there is a brief race condition window during which multiple threads could perform redundant initialization. If the file system implementation has expensive initialization logic, then this is wasteful. This issue proposes to eliminate that race condition and guarantee initialization of only a single instance. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
