Date Sat, 27 Jul 2013 19:07:48 GMT
Jerry He created HBASE-9060:

             Summary: EXportSnapshot job fails if target path contains percentage character
                 Key: HBASE-9060
                 URL: https://issues.apache.org/jira/browse/HBASE-9060
             Project: HBase
          Issue Type: Bug
          Components: snapshots
    Affects Versions: 0.94.10, 0.95.1
            Reporter: Jerry He
            Assignee: Jerry He
            Priority: Minor

Here is the stack trace:

        at org.apache.hadoop.hbase.snapshot.ExportSnapshot$ExportMapper.map(ExportSnapshot.java:98)

The problem is this code in copyData():
final String statusMessage = "copied %s/" + StringUtils.humanReadableInt(inputFileSize) +
                                   " (%.3f%%) from " + inputPath + " to " + outputPath;

Since we don't know what the path may contain that may confuse the formatter, we need to pull
that part out of the format string.

Also the percentage completion math seems to be wrong in the same code.
