Summary: when outputting XML, OfflineEditsViewer can't handle some edits containing non-ASCII strings Key: HDFS-4235 URL: https://issues.apache.org/jira/browse/HDFS-4235 Project: Hadoop HDFS Issue Type: Bug Reporter: Colin Patrick McCabe Priority: Minor It seems that when outputting XML, OfflineEditsViewer can't handle some edits containing non-ASCII strings. Example: {code} cmccabe@keter:/h> ./bin/hdfs oev -i ~/Downloads/current2/edits -o /tmp/u.xml 17:11:24,662 ERROR OfflineEditsBinaryLoader:82 - Got IOException at position 10593 Encountered exception. Exiting: SAX error: The character '�' is an invalid XML character java.io.IOException: SAX error: The character '�' is an invalid XML character at org.apache.hadoop.hdfs.tools.offlineEditsViewer.XmlEditsVisitor.visitOp(XmlEditsVisitor.java:119) at org.apache.hadoop.hdfs.tools.offlineEditsViewer.OfflineEditsBinaryLoader.loadEdits(OfflineEditsBinaryLoader.java:78) at org.apache.hadoop.hdfs.tools.offlineEditsViewer.OfflineEditsViewer.go(OfflineEditsViewer.java:142) at org.apache.hadoop.hdfs.tools.offlineEditsViewer.OfflineEditsViewer.run(OfflineEditsViewer.java:228) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:84) at org.apache.hadoop.hdfs.tools.offlineEditsViewer.OfflineEditsViewer.main(OfflineEditsViewer.java:237) {code} Probably, we forgot to properly escape and/or re-encode a filename before putting it into the XML. The other processors (stats, binary) don't have this problem, so it is purely an XML encoding issue. -- This message is automatically generated by JIRA.
