> Regex for Cmd parsing contains an error
> ---------------------------------------
>
> Key: HADOOP-5087
> URL: https://issues.apache.org/jira/browse/HADOOP-5087
> Project: Hadoop Core
> Issue Type: Bug
> Components: contrib/chukwa
> Environment: HADOOP-4947 use regex to parse chukwa commands but there's an error in the regex
> the current regex is:
> Pattern addCmdPattern = Pattern.compile("[aA][dD][dD]\\s+(\\S+)\\s+(\\S+)\\s+(.*\\S)?\\s*(\\d+)\\s*");
> does not correctly parsed this valid checkpoint entry:
> "ADD org.apache.hadoop.chukwa.datacollection.adaptor.filetailer.CharFileTailingAdaptorUTF8NewLineEscaped Syslog 0 /var/log/messages 114027"
> Parsing result:
> adaptorName org.apache.hadoop.chukwa.datacollection.adaptor.filetailer.CharFileTailingAdaptorUTF8NewLineEscaped
> dataType Syslog
> params 0 /var/log/messages 11402
> offset 7
> Instead of:
> adaptorName org.apache.hadoop.chukwa.datacollection.adaptor.filetailer.CharFileTailingAdaptorUTF8NewLineEscaped
> dataType Syslog
> params 0 /var/log/messages
> offset 114027
> The correct regex is: "[aA][dD][dD]\\s+(\\S+)\\s+(\\S+)\\s+(.*\\s)?\\s*(\\d+)\\s*"
> Example of parsing: "ADD org.apache.hadoop.chukwa.datacollection.adaptor.MySpecificAdaptor Syslog 0 my param1 param2 /var/log/messages 114027";
> Parsing result:
> adaptorName org.apache.hadoop.chukwa.datacollection.adaptor.MySpecificAdaptor
> dataType Syslog
> params 0 my param1 param2 /var/log/messages
> offset 114027
