apache pig - Making Pig 0.12 work with hadoop 2.2.0 -


i have hadoop 2.2.0 running on remote cluster , pig 0.12 on separate machine. need make pig communicate hadoop , first steps seems to build pig 0.12 hadoop 2.2.0. here did:

  1. in ivy/libraries.properties changed hadoop-core.version, hadoop-common.version, hadoop-hdfs.version, hadoop-mapreduce.version 2.2.0.
  2. in ivy.xml replaced hadoop-core dependency hadoop-client dependency.
  3. build pig using "ant clean jar-all -dhadoopversion=23"

when run "pig" command line following error:

error 2998: unhandled internal error. org/apache/hadoop/hdfs/distributedfilesystem  java.lang.noclassdeffounderror: org/apache/hadoop/hdfs/distributedfilesystem         @ org.apache.pig.backend.hadoop.executionengine.hexecutionengine.init(hexecutionengine.java:173)         @ org.apache.pig.backend.hadoop.executionengine.hexecutionengine.init(hexecutionengine.java:122)         @ org.apache.pig.impl.pigcontext.connect(pigcontext.java:301)         @ org.apache.pig.pigserver.<init>(pigserver.java:222)         @ org.apache.pig.pigserver.<init>(pigserver.java:207)         @ org.apache.pig.tools.grunt.grunt.<init>(grunt.java:47)         @ org.apache.pig.main.run(main.java:538)         @ org.apache.pig.main.main(main.java:156) caused by: java.lang.classnotfoundexception: org.apache.hadoop.hdfs.distributedfilesystem         @ java.net.urlclassloader$1.run(urlclassloader.java:202)         @ java.security.accesscontroller.doprivileged(native method)         @ java.net.urlclassloader.findclass(urlclassloader.java:190)         @ java.lang.classloader.loadclass(classloader.java:306)         @ sun.misc.launcher$appclassloader.loadclass(launcher.java:301)         @ java.lang.classloader.loadclass(classloader.java:247)

just building command ant clean jar-all -dhadoopversion=23 or ant jar-withouthadoop –dhadoopversion=23 not enough if using maven dependencies in project. need install jar created in local maven repo or use dependency (notice "classifier" tag hadoop2) in pom.xml

<dependency>   <groupid>org.apache.pig</groupid>   <artifactid>pig</artifactid>   <version>0.13.0</version>   <classifier>h2</classifier> </dependency>

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

i'm integrating okta own idp server using okta's api. i'm implementing authorization code flow following steps below: in own server, use /api/v1/authn endpoint sessiontoken. use sessiontoken obtain authorization calling endpoint: /oauth2/v1/authorize?client_id=" + clientid + "&sessiontoken=" + sessiontoken + "&response_type=code&response_mode=query&scope=openid&redirect_uri=" + redirecturl + "&state=evanyang&nonce=" it's supposed return response status code 302 , location header containing redirect url code value. however, keep getting response status code 200 , without location header, html body saying "you using unsupported browser." , "javascript disabled on browser." according api documentation: http://developer.okta.com/docs/api/resources/oidc.html#authentication-request , sessiontoken parameter sufficient this: an okta one-time sessiontoken. allows api-based

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
