i trying join table based on previous month after several failed attempts i'm not sure how solve this. i have larger query join section pretty simple, first attempt this: left outer join (select user_id, coalesce(count(*),0) count_m,mth table_name group user_id,mth ) m on month(main_table.local_date) -1 = m.mth , m.user_id = main_table.user_id but of course if have date in january , subtract 1 0, not 12. the next attempt hive's datesub function: left outer join (select user_id, coalesce(count(*),0) count_m,mth table_name group user_id,mth ) m on month(date_sub(main_table.local_date,31)) = m.mth , m.user_id = main_table.user_id but again problem obvious - not every month has 31 days end problems dates previous month not correctly matched (although @ least solves january - december problem previous approach. i tried use case approach in on command, handle jan-dec problem, before realizing hive accept equi-joins. any appreciated. subtract number of...

git-rebase man page mentions -x<option> can passed git-merge . when/how exactly? i'd rebase applying patches recursive strategy , theirs option (apply whatever sticks, rather skipping entire conflicting commits). don't want merge, want make history linear. i've tried: git rebase -xtheirs and git rebase -s 'recursive -xtheirs' but git rejects -x in both cases. git rebase -xtheirs works in recent versions, except tree conflicts need resolved manually. need run git rebase -xtheirs --continue (with -x repeated) after resolving conflicts. you can use git v1.7.3 or later versions. git rebase -s recursive -x theirs ${branch} from git v1.7.3 release notes: git rebase --strategy <s> learned -x option pass options understood chosen merge strategy. nb: "ours" , "theirs" mean opposite of during straight merge. in other words, "theirs" favors commits on current branch. update: edited cl...

i diving in universe of graph databases , i'm amazed how powerful is. chose orientdb start first use case i'm not if domain applies specific section of app. an user follows user . an user can be part of conversation . a message can sent (with timestamp) conversation . a message can read (with timestamp) user . i'm worried end millions (even billions) of message nodes , sent or read edges affecting overall performance of system. messaging section not main concept of app, small portion of it. would problem orientdb handle? application graph database? thank patience, vinicius take @ suggested way use orientdb similar use case: http://orientdb.com/docs/last/chat-use-case.html

is there way move config app (app/config) above app folder? want deploy app folder without override config files on multiple instances of app. i not sure if possible. can adding (set of) custom config(s) config.php's always_load section. can add custom paths can loaded file, outside of application. while (partly) solves problem, might have better solution you: you can configure application per environment. apppath/config/production/*.php override default configuration. if don't want version control folder, can add .gitignore. if deployment process smart enough, can configure preserve configuration files between deployments. activate production environment, need set fuel_env environment variable production.

when jdk includes jre execution of code, why have download jre separately execute java code doubt that's bothering me as far remember depends on os, browser , jdk version. eg. if you're using 64-bit os , installed 64-bit jdk, using 32-bit browser, might have install 32-bit jre if need java support in browser. otherwise separate jre installation should not required, since jdk installation installs jre.

obviously hbase has no implicit way of doing this. next thought using acls @ cell level. unfortunately i've seen setting acls specific user or map of users/permissions. there way allow users specific group have permissions? group names prefixed using @ in grant command. grant '@mygroup', 'rw' this , this talks in more detail. in documentation given how manage group roles not info implementation, below 8.2.2 - point 3 hbase managed "roles" collections of permissions: not model "roles" internally in hbase begin with. instead allow group names granted permissions, allows external modeling of roles via group membership. groups created , manipulated externally hbase, via hadoop group mapping service.
