Hadoop and MySQL Integration -

-

we implement hadoop on our system improve performance.

the process works this: hadoop gather data mysql database process it. output exported mysql database.

is implementation? improve our system's overall performance? requirements , has been done before? tutorial help.

thanks

altough not regular hadoop usage. migh make sense in following scenario:
a) if have way partition data inputs (like existing partitioning).
b) processing of each partition relatively heavy. give number of @ least 10 seconds of cpu time per partition.
if both conditions met - able apply desired amount of cpu power make data processing.
if doing simple scan or aggregation - think not gain anything. on other hand - if going run cpu intensive algorithms on each partition - indeed gain can significant.
mention separate case- if processing require massive data sorting. not think mysql in sorting billions of records. hadoop it.

i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt

Determine if a XmlNode is empty or null in C#? -

the following code takes xmlnode data type , populates dataset object xmlnode content. write dataset's content file. public void populatedataset(xmlnode node) { xmlnodereader reader = new xmlnodereader(node); dataset ds = new dataset(); ds.readxml(reader); system.guid guid = system.guid.newguid(); string name = string.format("{0}{1}_{2}.xml", utility.xmloutputpath, utility.xmloutputfilename, guid.tostring()); //need write "node empty" file if xmlnode object empty of null ds.writexml(name, xmlwritemode.ignoreschema); } the problem encountered 1 scenario not write content file. how determine if xmlnode object null or empty? you can check if node parameter null or has innertext or innerxml properties null or empty, when enter method before creating xmlnodereader .
