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

             Summary: json2sstable can not read from a pipe even if -n and -s are specified.
                 Key: CASSANDRA-5733
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5733
             Project: Cassandra
          Issue Type: Improvement
          Components: Tools
    Affects Versions: 1.2.6
            Reporter: Steven Lowenthal
            Priority: Minor


SSTableImport.importSorted always opens the file twice even if the number of keys are specifed.  I changed this to only open the file a second time when -n is not specified.

I moved the second parser = getparser ...  call inside the if (keyCountToImport == null) block.

        if (keyCountToImport == null)
        {
            keyCountToImport = 0;
            System.out.println("Counting keys to import, please wait... (NOTE: to skip this use -n <num_keys>)");

            parser.nextToken(); // START_ARRAY
            while (parser.nextToken() != null)
            {
                parser.skipChildren();
                if (parser.getCurrentToken() == JsonToken.END_ARRAY)
                    break;

                keyCountToImport++;
            }
          parser = getParser(jsonFile); // renewing parser only if we read the file already - to support streaming.
        }
