anybody, please explain what's difference between signatures. when open 1 pdf document - adobe acrobat 9 shows message "at least 1 signature has problems" if open other pdf message "at least 1 signature requires validating". seems both pdfs signed self-signed certificates, messages not same. difference extremely significant our business. please help. making comment actual answer at least 1 signature has problems implies adobe acrobat has tried verify signature failed doing so. at least 1 signature requires validating implies adobe acrobat has not tried verify signature and, therefore, has not yet decided whether fail or not. whether or not adobe reader / acrobat tries verify signature depends on filter , subfilter entries of signature dictionary: if reader / acrobat knows them, automatically tries verify signature (unless configuration settings changed). if knows subfilter not filter , not try verify automatically @ least offers verif...

what difference between mapper , map task? similarly, reducer , reduce task? also, how number of mappers,maptasks,reducers,reducetasks determined during execution of mapreduce task? give interrelationships between them if there any. simply map task instance of mapper. mapper , reducer methods in mapreduce jobs. when run mapreduce job, number of map tasks spawned depends on number blocks(number of blocks depend on input splits) in input. number of reduce tasks can specified in mapreduce driver code. either can specified setting property mapred.reduce.tasks in job configuration object or org.apache.hadoop.mapreduce.job#setnumreducetasks(int reducercount); method can used. in old jobconf api setnummaptasks() method there. setnummaptasks() method removed in new api org.apache.hadoop.mapreduce.job with intension of number of mappers should calculated based on input splits.

i using grep string this: ans_length=266.50 use sed digits: 266.50 this full command: grep --text 'ans_length=' log.txt | sed -e 's/[^[[:digit:]]]*//g' the result : 26650 how can line changed result still shows separator: 266.50 you don't need grep if going use sed . use sed' // match lines need print. sed -n '/ans_length/s/[^=]*=\(.*\)/\1/p' log.txt -n suppress printing of lines not match /ans_length/ using captured group print value next = sign. p flag @ end allows print lines matches our // . if grep happens support -p option can do: grep -op '(?<=ans_length=).*' log.txt (?<=...) look-behind construct allows match lines need. requires -p option -o allows print value part.

does postgresql have pseudo-column "level" in oracle? if not, how can create column similar "level"? well, first of all, postgres not have hierarchical queries . no connect by , therefore no level . you can similar things recursive cte , level column that's incremented every recursion. query in oracle: select employee_id, last_name, manager_id, level employees connect prior employee_id = manager_id; .. translated recursive cte in postgres: with recursive cte ( select employee_id, last_name, manager_id, 1 level employees union select e.employee_id, e.last_name, e.manager_id, c.level + 1 cte c join employees e on e.manager_id = c.employee_id ) select * cte;
