-------------------------------------

             Summary: TeeOutputStream.close() should close every wrapped output
                 Key: HDFS-17979
                 URL: https://issues.apache.org/jira/browse/HDFS-17979
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: tools
    Affects Versions: 3.4.1
            Reporter: Sanjay Malakar


The OfflineEditsViewer \{{org.apache.hadoop.hdfs.tools.offlineEditsViewer.TeeOutputStream.close()}} closes its wrapped output streams in a for-each loop. If one \{{java.io.OutputStream.close()}} call throws \{{java.io.IOException}}, the loop exits and every later output is left open.

{\{close()}} should attempt every output, keep the first \{{java.io.IOException}}, attach later failures as suppressed exceptions, and throw the first one after every output has been attempted. This mirrors the fix in ZOOKEEPER-5055 for \{{FileTxnLog.close()}}.
