             Summary: Ensure FileTxnLog.close() closes every stream
                 Key: ZOOKEEPER-5055
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-5055
             Project: ZooKeeper
          Issue Type: Bug
          Components: server
            Reporter: Sanjay Malakar


{{org.apache.zookeeper.server.persistence.FileTxnLog.close()}} closes {{logStream}} and the {{streamsToFlush}} queue sequentially. If any {{java.io.FileOutputStream.close()}} call throws {{{}java.io.IOException{}}}, the method exits immediately and does not attempt to close the remaining file streams. This can leak file descriptors during transaction-log shutdown.

{{org.apache.zookeeper.server.persistence.FileTxnLog.close()}} should attempt every close operation, preserve the first {{{}java.io.IOException{}}}, attach later failures as suppressed exceptions, and throw only after all streams have been attempted.
