[jira] [Commented] (HADOOP-13607) Specify and test contract for FileSystem#close.

    [ https://issues.apache.org/jira/browse/HADOOP-13607?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15488263#comment-15488263 ] 

Chris Nauroth commented on HADOOP-13607:
----------------------------------------

I'd also like to add tests to {{AbstractContractCreateTest}} and {{AbstractContractOpenTest}} that test idempotence of the stream {{close}} methods.

> This issue proposes to enhance the {{FileSystem}} specification by describing the expected semantics of {{FileSystem#close}} and adding corresponding contract tests.  Notable aspects are that the method must be idempotent as dictated by {{java.io.Closeable}} and closing also interacts with the delete-on-exit feature.
